Postman collection

Import the HelloCRM API collection into Postman to try endpoints with your team API key. The collection includes conversations, messaging, templates, contacts, companies, products, deals, and quotes.

1. Import the collection

1. Open Postman and click Import.
2. Select Link and paste this URL:

Or download the file: hello-crm.postman_collection.json

2. Set up your environment

In Postman, create an environment (or edit collection variables) with:

• baseUrl — https://api.hellocrm.ai (no trailing slash)
• apiKey — your HelloCRM team API key (Settings → API keys in the app)

Requests send your key in the x-api-key header automatically.

3. Send a request

Pick any request in the collection, choose your environment, and click Send. Start with Contacts or Conversations if you are new to the API.

Optional headers

• Content-Type: application/json — included on requests with a body.
• Idempotency-Key — use a unique value when creating records or sending messages so retries do not duplicate work.
