    Hello Team,

    Customer would like to integrate their web services into some inbound flow. This web service is using OAuth 2 for authentification. I was provided the following information :

    loginUrl : https://xxxxxxxxxx.com/maam/v1/token clientId : xxxxxxxxxx clientSecret : xxxxxxxxxxxxx scope : xxxxxxxxx

    So I created the following Integration :

    And it created the following Data Action for Custom Auth:

    If I tried like this, I got the following error (which was expected) :

    { "status": 400, "code": "bad.request", "message": "The request could not be understood by the server due to malformed syntax.", "messageParams": {}, "contextId": "6ceb9b2d-7538-4aa3-bed3-9040f6521632", "details": [ { "errorCode": "ACTION.REMOTEENDPOINT" } ], "errors": [ { "status": 400, "code": "BADREQUEST", "message": "REST call for action execute failed. Message:Request to backend service failed. Response from web service: {\n\t\"error\": \"invalid_scope\"\n} [6ceb9b2d-7538-4aa3-bed3-9040f6521632]", "messageParams": {}, "details": [], "errors": [] } ] }

    I then filled the scope in the "Request Body Template" part:

    But then I got the following error:

    { "status": 400, "code": "bad.request", "message": "The request could not be understood by the server due to malformed syntax.", "messageParams": {}, "contextId": "982fd4a6-532f-4ee4-875b-2f12587c809a", "details": [ { "errorCode": "ACTION.REMOTEENDPOINT" } ], "errors": [ { "status": 400, "code": "BADREQUEST", "message": "REST call for action execute failed. Message:Request to backend service failed. Response from web service: {\n\t\"error\": \"invalid_grant\"\n} [982fd4a6-532f-4ee4-875b-2f12587c809a]", "messageParams": {}, "details": [], "errors": [] } ] }

    I tried various syntax:

    "granttype"="clientcredentials", "scope"="urn:axa:france:fca-sdm-cst"

    Or

    { "granttype":"clientcredentials", "scope":"urn:axa:france:fca-sdm-cst" }

    But still got the same error invalid_grant

    I even try to put the scope in the integration:

    Or

    But it doesn't seem to be taken into account since I have the following error:

    { "status": 400, "code": "bad.request", "message": "The request could not be understood by the server due to malformed syntax.", "messageParams": {}, "contextId": "0a24a389-d7bf-441c-961f-ff92c01f49ae", "details": [ { "errorCode": "ACTION.REMOTEENDPOINT" } ], "errors": [ { "status": 400, "code": "BADREQUEST", "message": "REST call for action execute failed. Message:Request to backend service failed. Response from web service: {\n\t\"error\": \"invalid_scope\"\n} [0a24a389-d7bf-441c-961f-ff92c01f49ae]", "messageParams": {}, "details": [], "errors": [] } ] }

    On Postman, it's working fine and I can manage to get a token :

    Anyone would know if I'm doing wrong something ?

    Cheers, Valéry Chhoa

    Hello Valery,

    You should put clientId, clientSecret and scope in Request Body template, and with '&' to separate parameters

    Hope it helps :slight_smile:
