Using OAuth with password grant type

(1) Share

Report

Posted on by Mark Carrington

I have an API I am trying to build a connector for. The API uses OAuth, but requires the password grant type. I can’t see an option for this when setting up the security settings on the connector.

I can set up the connector as having no authentication and then create an action that calls the token endpoint and I successfully get the access token back, but I then can’t use that to set the Authorization header on subsequent actions (and my username and password would become part of the flow as well, which isn’t great)

Is there any other way of approaching this?

Hi @MarkData8 ,

From the doc on creating a custom connector, it seems that there is no option for requiring the password grant type:

https://docs.microsoft.com/en-us/connectors/custom-connectors/define-blank#specify-authentication-type

I will help do more research on this issue and then back to you.

Best regards,

Mabel

Has there been an update to this issue. I am also working on building a Custom Connector for an API that requires the grant type to be set. It seems to be a common requirement on APIs.

Bump. I am having the same issue. I need to pass a "type" parameter to my authorization URL. I cannot get past the authorization stage for my custom connector without this.

Hi,
it's been a few years, but I'll try my luck anyway. Could anyone use the password flow?
If I modify the Swagger definition, I can change it to password flow
securityDefinitions > oauth2-auth > flow
but it leads to an error, which doesn't say exactly what the problem is.

Hi @sammysword nope, https://powerusers.microsoft.com/t5/Using-Connectors/Using-OAuth-with-password-grant-type/m-p/2569310/emcs_t/S2h8ZW1haWx8bWVudGlvbl9zdWJzY3JpcHRpb258TFJTWkExRU1BVTIzT0R8MjU2OTMxMHxBVF9NRU5USU9OU3xoSw#M21507 It looks like just "authorization code flow" or API-Key is supported by custom connectors supported.
