I will do hubspot api integration, webhooks and two way data sync
Level 1
Has met certain performance criteria and shows strong potential in the marketplace.
About this Gig
Your HubSpot data is stuck in one place and someone on your team is copying records by hand.
I build HubSpot API integrations and webhook automations that connect HubSpot to the systems you already run: Sonar, Salesforce, Stripe, QuickBooks, Shopify, Xero, Twilio, Airtable, SQL databases, and custom internal apps.
What I do:
- Private App + OAuth setup (no legacy API keys)
- Two-way sync for contacts, deals, companies and custom objects
- Webhook listeners with retries, idempotency and failure logging
- Rate-limit handling, field mapping, sandbox testing before production
- n8n / Make when custom code is overkill
What you get: a field-mapping sheet before I write code, a sandbox demo before go-live, error alerts you can actually read, and a handover doc so your next developer isn't guessing.
Stack: Node.js, Python, PHP. 5+ years building on HubSpot CRM, Marketing Hub and Sales Hub APIs.
Message me with the two systems you want connected and the fields that matter. I'll send back the approach, the edge cases, and a fixed timeline before you order.

FAQ
Which systems can you connect to HubSpot?
Anything with a REST API, plus SQL databases, SFTP drops and file exports. Common ones: Salesforce, Stripe, QuickBooks, Xero, Shopify, Twilio, Airtable, NetSuite and custom internal apps. If the system has no API, I'll tell you that on day one instead of after you order.
Do you use HubSpot API keys, private apps or OAuth?
Private app access tokens for single-account work, OAuth for anything installed on multiple portals. HubSpot retired API keys, so any integration still running on one is overdue for migration. Tokens are stored in environment variables, never hardcoded in the repo.
Can you build a two-way sync between HubSpot and my system?
Yes. Two-way sync needs conflict rules decided upfront: which system wins on a field clash, how deletes propagate, and whether updates loop back. I agree those rules with you in a mapping sheet before writing code, because retrofitting them later means re-syncing your data.
What happens when HubSpot's API rate limit is hit?
The integration backs off and retries rather than dropping records. Private apps get 100 requests per 10 seconds on Free and Starter, 190 on Pro and Enterprise, with daily caps shared across the account. Batch endpoints move up to 100 records per call to stay under it.
Why is my HubSpot sync slow or throwing 429 errors?
Usually the Search API. It's capped at 5 requests per second per account, separate from and stricter than the main burst limit, and most sync tools route bulk lookups through it. The fix is batch endpoints, caching IDs locally, and webhooks instead of polling.
Can you use HubSpot webhooks instead of polling for changes?
Yes, and it's usually the right call. Webhook subscriptions push contact, company, deal and ticket changes to your endpoint instead of you polling on a timer. That cuts API usage sharply. Each app supports up to 1,000 subscriptions.
Can you sync custom objects and custom properties?
Yes. Custom objects, custom properties, associations and pipeline stages all sync the same way as standard objects. Property internal names, not labels, are what the API uses, so the mapping sheet lists both to stop the wrong field being written to.
Do you use n8n and Make, or custom code?
Whichever fits. n8n or Make when the logic is simple and your team wants to edit it without a developer. Custom Node.js or Python when you need real error handling, high volume or logic those tools can't express. I'll tell you which one your project needs and why.
Do I get the code, and will you test before going live?
Yes to both. Everything is built against a HubSpot sandbox or test portal first and demoed before it touches production. You get the source, the field mapping sheet and setup docs, so your own developer can maintain it. No hosted black box you have to keep paying for.
