Connect Sales Tools
Help the user design and implement integrations between sales tools — from choosing the right integration method through trigger/action design, field mapping, and error handling. This skill covers webhooks, Zapier/Make, native integrations, and custom API pipelines.
Step 1 — Gather context
If references/learnings.md exists, read it first for accumulated knowledge.
Ask the user:
- What are you connecting?
- Source tool (where the event happens): Mailshake, Apollo, Salesloft, Smartlead, Lemlist, Yesware, Groove.cm, Mixmax, Reply.io, Woodpecker, Hunter.io, Seismic, Tomba, Prospeo, Seamless.AI, SafetyMails, Closum, Omnisend, Mailchimp, SendGrid, Postmark, Customer.io, Mailgun, Klaviyo, ActiveCampaign, Outscraper, Enrich.so, Minelead, Lobstr.io, GetProspect, Skrapp, OpenWeb Ninja, Anymail Finder, ZeroBounce, Snov.io, LeadMagic, ZoomInfo, Clearbit, RB2B, 6sense, Brevo, Braze, Iterable, GetResponse, SendPulse, Clay, HubSpot, Salesforce, Qwilr, RudderStack, Boomi, Workato, Celigo, SnapLogic, Jitterbit, Tray, Informatica, TIBCO, other - Destination tool (where the action should happen): Salesforce, HubSpot, Slack, Pipedrive, other - Is this one-way or bidirectional?
- What should trigger the integration?
- A) Email reply received - B) New lead captured - C) Meeting booked - D) Deal stage changed - E) Contact created/updated - F) Sequence/cadence completed - G) Form submission - H) Custom event — describe it
- What should happen when triggered?
- A) Create a record (contact, task, deal, activity) - B) Update a record (field change, stage change, owner change) - C) Send a notification (Slack, email, SMS) - D) Enroll in a sequence/cadence - E) Multiple actions — describe
- What's your technical comfort level?
- A) No-code — Zapier, Make, native integrations only - B) Low-code — comfortable with basic API calls, can follow docs - C) Code — can build custom integrations with API + webhooks
- What's your current stack? (list all sales/marketing/CRM tools in use)
If the user's request already provides most of this context, skip directly to the relevant step. Lead with your best-effort answer using reasonable assumptions (stated explicitly), then ask only the most critical 1-2 clarifying questions at the end — don't gate your response behind gathering complete context.
Step 2 — Integration architecture
Choose the right integration method based on complexity and technical requirements.
Decision matrix
| Method | Best for | Technical skill | Cost | Reliability |
|---|---|---|---|---|
| Native integration | CRM sync, built-in connectors | None | Free (included) | High |
| Zapier / Make | Multi-step workflows, no-code | Low | $20-100/mo | High |
| Webhooks + handler | Real-time events, custom logic | Medium | Free-low | Medium-high |
| Custom API pipeline | Complex transformations, high volume | High | Varies | Depends on implementation |
Native integrations — always check first
Before building anything custom, check if a native integration exists:
For a complete lookup table of 240+ native integrations across all supported tools, see references/integrations.md.
Rule: If a native integration covers your use case, use it. Native integrations handle auth, retry, and error handling automatically. Only go custom when native doesn't support your specific trigger or action.
Step 3 — Common integration patterns
Lead/reply → CRM record + notification
Trigger: Reply received in Mailshake/Apollo/Salesloft Actions:
- Create or update contact in CRM
- Create activity/task on the contact record
- Send Slack notification to rep
Implementation options:
- Zapier: Trigger = Mailshake "Reply Received" → Actions = Salesforce "Create Task" + Slack "Send Message"
- Webhook: Mailshake push event (Reply) → your endpoint → Salesforce API + Slack API
- Native: Mailshake-Salesforce integration (auto-syncs replies as activities)
Meeting booked → CRM + sequence exit
Trigger: Meeting booked (Calendly, Chili Piper, or CRM scheduler) Actions:
- Update contact status/stage in CRM
- Remove from active sequence/cadence
- Create deal/opportunity
- Notify AE
CRM status change → sequence enrollment
Trigger: Lead status changes to "MQL" in CRM Actions:
- Enroll contact in outbound sequence (Apollo, Salesloft, Mailshake)
- Assign to appropriate rep based on routing rules
Implementation options:
- Zapier/Make (no-code): HubSpot "Lifecycle Stage Change" trigger → Apollo "Add Contact to Sequence" action. Easiest setup, handles auth automatically.
- CRM webhook + custom API (low-code): HubSpot workflow triggers webhook → your endpoint calls Apollo
POST /contacts/add_to_emailer_campaign. More control over field mapping, error handling, and conditional logic. - Native CRM workflow (if supported): Some CRM-to-engagement-tool integrations support enrollment triggers natively — check Settings > Integrations before building custom.
Error handling for sequence enrollment:
- Duplicate contact: Check if contact already exists in the engagement tool before creating — use "Find or Create" logic
- Already enrolled: The API may reject enrollment if the contact is active in another sequence — handle gracefully (log, skip, or queue for later)
- Sequence capacity / enrollment limits: Sequences may have max enrollment caps or daily add limits. Monitor the API response for limit errors and implement a retry queue for overflow.
- Re-qualification: If a lead was previously disqualified and re-enters MQL, decide whether to re-enroll or skip (prevent spamming the same contact)
Deal stage change → stakeholder notification
Trigger: Deal moves to "Proposal Sent" or "Negotiation" in CRM Actions:
- Notify relevant stakeholders in Slack
- Create follow-up task for rep
- Trigger proposal creation in Qwilr (see
/sales-qwilr-automation)
Multi-tool activity sync
Trigger: Any activity logged in engagement tool (email sent, call made, meeting held) Action: Sync activity to CRM as a completed task/activity
Key considerations:
- Define sync direction (one-way vs bidirectional)
- Map fields between tools (Salesloft "Call" → Salesforce "Task" with type "Call")
- Handle duplicates (check if activity already exists before creating)
Step 4 — Platform webhook reference
For platform-specific webhook configs, API integrations, and native connector details, see references/platforms.md.
Step 5 — Data sync best practices
Define source of truth
Before building any bidirectional sync, decide which tool is the source of truth for each field:
| Data type | Typical source of truth | Why |
|---|---|---|
| Contact info (name, email, phone) | CRM (Salesforce/HubSpot) | CRM is the canonical record |
| Activity data (emails, calls) | Engagement tool (Apollo/Salesloft/Mailshake) | Activity originates in the engagement tool |
| Deal/opportunity | CRM | Revenue data lives in CRM |
| Lead score | MAP or CRM | Scoring logic runs in MAP/CRM |
| Sequence status | Engagement tool | Sequence state managed by engagement tool |
Conflict resolution
- Last-write-wins: Simple but dangerous — later update overwrites earlier one
- Source-of-truth wins: Designated source always overwrites destination
- Field-level rules: Different rules per field (e.g., CRM wins for phone, engagement tool wins for email status)
- Manual review: Flag conflicts for human review (safest for critical fields)
Deduplication
- Match keys: Email address (primary), company domain + name (secondary)
- When to dedup: Before creating records, during sync, and periodically as maintenance
- Tools: Native CRM dedup (Salesforce Duplicate Rules, HubSpot dedup tool), or third-party (Dedupely, RingLead)
Error handling
- Retry logic: Implement exponential backoff for failed API calls (1s, 2s, 4s, 8s)
- Dead letter queue: Store failed events for manual review and replay
- Alerting: Slack/email notification when sync errors exceed threshold
- Monitoring: Track sync success rate, latency, and error types weekly
Gotchas
- Check native integrations first. Don't build a Zapier workflow for something the tools already handle natively. Native integrations are more reliable, handle edge cases better, and don't cost extra. Check Settings > Integrations in both tools before going custom.
- Respect API rate limits. Every tool has rate limits — Mailshake (100/min), Apollo (~200/min on Pro), Salesforce (varies), HubSpot (100/10s). High-volume syncs that ignore rate limits will get throttled or blocked. Always implement batching and backoff.
- Define source of truth before bidirectional sync. Bidirectional sync without clear field-level ownership creates data ping-pong (A updates B, B updates A, loop). For every field that syncs bidirectionally, document which tool wins on conflict.
- Self-improving: If you discover something not covered here, append it to
references/learnings.mdwith today's date.
Before recommending a specific platform skill
This skill covers a strategy domain across many platforms. Before pointing the user to any specific platform skill (any /sales-{platform} listed in ## Related skills, e.g., /sales-mailshake, /sales-klaviyo, /sales-apollo), read that platform skill's actual SKILL.md first. The 1-line description in ## Related skills is enough to *identify* a candidate — it's not enough to *commit* to it or to write a prompt that invokes it well.
How to read it:
- If
~/.claude/skills/{skill-name}/SKILL.mdexists locally,Readit. - For
sales-*skills,WebFetchdirectly from this repo:https://raw.githubusercontent.com/sales-skills/sales/main/skills/{skill-name}/SKILL.md— e.g., forsales-mailshake:https://raw.githubusercontent.com/sales-skills/sales/main/skills/sales-mailshake/SKILL.md. - For non-
sales-*skills (third-party), look up{org}/{repo}in~/.claude/skills/sales-do/references/skill-sources.mdif installed and fetch the sameskills/{skill-name}/SKILL.mdpath under that repo.
After reading, ground your recommendation in something concrete from the SKILL.md (its scope, a sub-flow, its argument-hint shape, or a "Do NOT use for..." negative trigger). Align any generated invocation with the platform skill's argument-hint. If the platform skill turns out not to fit the user's situation, swap to another or handle the question here directly rather than recommending a poor fit.

Examples
Example 1: Mailshake reply → Salesforce + Slack
User says: "When someone replies to my Mailshake campaign, I want to create a task in Salesforce and get a Slack notification." Skill does:
- Checks if Mailshake-Salesforce native integration covers this (it does for activity sync)
- Recommends native for Salesforce + Zapier for Slack notification
- Provides Zapier workflow: Mailshake "Reply" trigger → Slack "Send Message" action
- Configures field mapping for the Salesforce activity Result: Reply-to-task sync via native integration, Slack alert via Zapier
Example 2: Salesloft activity → HubSpot
User says: "I need to sync all Salesloft activity to HubSpot so our marketing team can see sales touchpoints." Skill does:
- Checks native integration (Salesloft-HubSpot integration exists)
- Walks through native integration setup and field mapping
- Defines sync direction (Salesloft → HubSpot, one-way for activity)
- Addresses dedup and conflict resolution Result: Native integration configured with clear sync direction and field mapping
Example 3: HubSpot MQL → Apollo sequence
User says: "When a lead hits MQL status in HubSpot, I want to auto-enroll them in an Apollo sequence." Skill does:
- Designs trigger: HubSpot workflow on lifecycle stage = MQL
- Recommends Zapier (HubSpot trigger → Apollo "Add Contact to Sequence" action)
- Provides field mapping from HubSpot to Apollo contact fields
- Adds error handling (what if contact already exists in Apollo, what if sequence is full) Result: MQL-triggered enrollment with field mapping and error handling
Troubleshooting
Sync creating duplicates
Symptom: Same contact appearing multiple times in destination tool Cause: Missing dedup logic — sync creates new records instead of matching existing ones Solution: Add matching/dedup step before create. Match on email address (primary key). Use CRM's native dedup rules. For Zapier, use "Find or Create" actions instead of "Create."
Events not firing
Symptom: Webhook or trigger not executing when expected Cause: Webhook URL misconfigured, event type wrong, or tool's webhook delivery failing Solution: Check webhook logs in the source tool. Test with a webhook debugging tool (webhook.site or RequestBin). Verify the event type matches exactly. Check if the webhook was disabled after errors.
Rate limit errors in high-volume sync
Symptom: 429 errors, sync falling behind, or events being dropped Cause: Sending too many API requests too quickly Solution: Implement batching (batch multiple records per request where API supports it). Add exponential backoff on 429 responses. Reduce sync frequency (every 5 min instead of real-time). Use bulk API endpoints where available.
