Invalid Token

401integration

https://inputbuffer.io/docs/api/problems/invalid-token

What it means

The token parsed correctly, but doesn't match an active token on this account.

This usually points at your integration's setup rather than anything the end user did. Show the end user a generic message like "Something went wrong on our end.", and log detail for your own debugging.

How to fix it

  1. 1.

    The token was copied incorrectly or truncated.

    Create a new token in Settings → API Tokens and copy the full value. It's shown only once.

  2. 2.

    The token was revoked. (Revoked and invalid tokens return the same error on purpose.)

    Create a new token. Revoked tokens can't be restored.

Where this happens

Enforced by shared authentication middleware before any endpoint-specific code runs. Every /api/v0/ request made with a Bearer token can return this.
