Overview

This article provides how to troubleshoot an issue on calling the CircleCI APIs. When you get the following error message, you might need to check the header.

"message" : "You must log in first."

Check which authorization method used for the request

There are various ways to authorize the API request (please refer to the document for details):

• api_key_header
• basic_auth
• api_key_query

Please check which method you are using for calling the API request and whether it following a correct syntax. For instance, if you want to use a personal API token, a request should look like this:

curl --request GET \
  --url 'https://circleci.com/api/v2/pipeline?org-slug=github/org_name&mine=false' \
  --header 'Circle-Token: CCIPAT_xxxxxx'
