LinkedIn leads will fail to be retrieved if a 400-level error has been detected. This means a Refresh Token, or an Access Token has been revoked by LinkedIn, thereby interrupting delivery of leads. Typically, this may have occurred for one of the following reasons:
· Technical or policy reasons, per LinkedIn terms.
· Deliberate revocation by the User of Refresh or Access Tokens due to Security concerns.
· Inadvertent revocation by the User while changing permissions.
Error codes that illustrate an invalid token
| Error Code | |
| 401 | Unauthorized |
| 403 |
Access Denied |
| 404 | Resource Not Found |
401 Unauthorized
| Error Type | Fix |
| Invalid access token | Incorrect access token, make sure you follow the authentication procedure to get a correct access token. |
| Expired access token | The access token has expired, see how to refresh your access token |
| The token has been revoked | The access token has been revoked by the member from their privacy settings on LinkedIn’s website. To continue using your application, the member has to re-authenticate to get a new access token for your application. |
403 Access Denied
When your application makes an API call with a member’s access token, LinkedIn checks if the access token has permission to access the API. If the access token does not have the correct permissions, a 403 Access Denied error is returned
404 Resource Not Found
In some cases (Ads, for example), a 404 error is returned when attempting to access a restricted API.
