Hi folks,

I'm trying to see if I can send POST request with content type 'application/x-www-form-urlencoded' to IBM Datapower.
Using REST Request node, it looks like IBM AppConnect does not currently offer support for "formData". 

LocalEnvironment

                Destination

                                                REST

                                                                                Request

                                                                                                                ContentType:CHARACTER:application/x-www-form-urlencoded

                                                                                                                Accept:CHARACTER:application/json

                                                                                                                BaseURL:CHARACTER:https://MASKED

                                                                                                                UserID:CHARACTER:MASKED

                                                                                                                Password:CHARACTER:MASKED

                                                                                                                Parameters

                                                                                                                                password:CHARACTER:MASKED

                                                                                                                                client_id:CHARACTER:MASKED

                                                                                                                                client_secret:CHARACTER:MASKED

                                                                                                                                grant_type:CHARACTER:MASKED

                                                                                                                                username:CHARACTER:MASKED

                                                                                                                                acr_values:CHARACTER:MASKED

                                                                                                                                scope:CHARACTER:MASKED

Text:CHARACTER:Don't know how to propagate the value of this parameter

                                                                                                                                                                                                                Insert

                                                                                                                                                                                                                                                Type:INTEGER:5

My question is if there is any alternative method to post request with content type 'application/x-www-form-urlencoded'

Dear Michael,

Using HTTP Request Node, you can send POST requests with content type application/x-www-form-urlencoded.
DECLARE redirecturi,granttype,clientsecret,authcode,Data CHARACTER;
SET redirecturi = 'redirecturi';
SET granttype = 'authorization_code';
SET clientsecret = 'clientsecret'
SET authcode = 'authcode';

SET Data = 'redirect_uri=' || redirecturi || '&grant_type=' || granttype || '&client_secret=' || clientsecret || '&code=' || authcode;
SET OutputRoot.HTTPRequestHeader."Content-Type" = 'application/x-www-form-urlencoded';
SET OutputRoot.BLOB.BLOB = CAST(Data AS BLOB CCSID 1208);

Thanks Anoop, using OutputRoot.BLOB.BLOB with HTTP Request Node did create a valid request.

Dear Michael,

Using HTTP Request Node, you can send POST requests with content type application/x-www-form-urlencoded.

I'm not sure if it's the same for Rest Request Nodes.

DECLARE redirecturi,granttype,clientsecret,authcode,Data CHARACTER;
SET redirecturi = 'redirecturi';
SET granttype = 'authorization_code';
SET clientsecret = 'clientsecret'
SET authcode = 'authcode';

SET Data = 'redirect_uri=' || redirecturi || '&grant_type=' || granttype || '&client_secret=' || clientsecret || '&code=' || authcode;
SET OutputRoot.HTTPRequestHeader."Content-Type" = 'application/x-www-form-urlencoded';
SET OutputRoot.BLOB.BLOB = CAST(Data AS BLOB CCSID 1208);

t looks like AppConnect doesn't natively support application/x-www-form-urlencoded via formData, but you can still send it by manually building the payload. Just construct the key=value string in LocalEnvironment or a Compute node, set the Content-Type header, and send it as raw data. Datapower will accept it as long as the formatting is correct.

Hi Michael,
You're right-IBM App Connect's REST Request node doesn't natively support application/x-www-form-urlencoded as formData. A common workaround is to manually build the payload as a URL-encoded string (e.g., key1=value1&key2=value2) and set the Content-Type header explicitly. Alternatively, you can use a Compute node before the REST Request to construct the body and headers as needed. Hope this helps.

Hi Michael,
I understand the struggle - handling application/x-www-form-urlencoded POST requests can be tricky, especially when some platforms don't fully support formData.
One alternative I've seen is using a helper service or middleware to format and forward requests correctly.
