Use this page to understand which authentication values to send with each request and when an endpoint also requires an OAuth signature or user ID.
All requests to the MassiveMusic API must include your consumer key as the oauth_consumer_key parameter.
API keys are available under a commercial agreement. To discuss access to the platform, get in touch with us here.
If you want a working example of authenticated requests and request setup, see the Postman sample requests guide.
When you generate an OAuth 1.0 signature, include request body parameters in the signature base string only if the body is single-part and application/x-www-form-urlencoded. Do not include a JSON body in the signature base string.
Reference: here
In the API reference, icons indicate when an endpoint requires an OAuth signature or user ID:
| Icon | Description |
|---|---|
![]() | OAuth signature required |
![]() | User ID required |
