When a customer's credit card fails on Stripe, every minute counts. Manually checking payment logs and hunting for contacts in your CRM leads to revenue leakage.
In this article, we'll look at how to build an automated bridge using Make.com and HubSpot's REST API to instantly locate matching CRM contacts whenever a payment fails.
The Architecture Overview
Instead of relying on heavy third-party app connectors that can lag or require high-tier subscriptions, we handle this using a lightweight 2-step setup:
-
Webhook Listener: Catches the
customer_emailpayload from Stripe. - HTTP Request Engine: Sends a search query directly to HubSpot's v3 CRM search endpoint.
The 10-Line HTTP Payload
Here is the exact JSON structure used to query the HubSpot v3 Contacts Search endpoint (POST /crm/v3/objects/contacts/search):
json
{
"endpoint": "https://api.hubapi.com/crm/v3/objects/contacts/search",
"method": "POST",
"headers": {
"Authorization": "Bearer [YOUR_HUBSPOT_ACCESS_TOKEN_PLACEHOLDER]",
"Content-Type": "application/json"
},
"body": {
"filterGroups": [{
"filters": [{ "propertyName": "email", "operator": "EQ", "value": "{{customer_email}}" }]
}]
}
}
**Key Takeaways for Automation Developers**
Security First: Always isolate your Private Access Tokens in headers and use placeholders when building public blueprint templates.
Exact Matching: Using the EQ operator on the email property ensures zero false positives when linking billing events to CRM records.
Handling Responses: A successful lookup returns total: 1 along with the contact ID, allowing you to trigger instant internal alerts or automated recovery sequences.
