How to Get API Keys

Your API key (also called bearer token or partner token) is your authentication credential for making API requests. Here's how to get it.

Step 1: Register in Marketplace

Head over to the Marketplace registration page and sign up.

Two scenarios:

  • Building an integration for a client? Ask them to invite you to their location (they'll need your phone number or email).
  • Building your own app/product? Register on alteg.io — fill in your service name in the "Location name" field, and a Partner Program manager will reach out.

Step 2: Get Your API Key

Once registered, your API key appears automatically in the Account settings section of the Marketplace. No need to generate it manually — it's there right after signup.

Copy this token and use it in your API requests as the bearer token:

Authorization: Bearer <your-api-key>

Step 3: Get User Token (if needed)

Most endpoints require only the bearer token. But for endpoints that access business data (like appointments, clients, transactions), you'll also need a user token.

Get the user token by calling the authentication endpoint with your user credentials. The response includes the user token.

Then use both tokens in your requests:

Authorization: Bearer <partner-token>, User <user-token>
