InvalidAuthenticationToken message IDX14100 JWT is not well formed, there are no dots
Question:
When I try to send:
Set resp = http.PostJson2("https://graph.microsoft.com/v1.0/me/sendMail","application/json",json.Emit())
I am getting this response:
"error": {
"code": "InvalidAuthenticationToken",
"message": "IDX14100: JWT is not well formed, there are no dots (.).
The token needs to be in JWS or JWE Compact Serialization Format.
(JWS): 'EncodedHeader.EndcodedPayload.EncodedSignature'.
(JWE): 'EncodedProtectedHeader.EncodedEncryptedKey.EncodedInitializationVector.EncodedCiphertext.EncodedAuthenticationTag'.",
"innerError": {
"date": "2024-05-13T15:26:14",
"request-id": "...",
"client-request-id": "..."
Failed, response status code = 401
What am I doing wrong?
Answer:
It’s probably because you didn’t set the Authorization header with the correct value of the access_token. When you get an OAuth2 access token via the authorization code flow, or the client credentials code flow, you’ll get JSON formatted similar to this:
"token_type": "Bearer",
"scope": "...",
"expires_in": 4220,
"ext_expires_in": 4220,
"access_token": "<base64_header>.<base64_payload>.<base64_signature>",
"refresh_token": "...",
"id_token": "...",
"expires_on": "1666052240"
The “access_token” is a JWT composed of 3 base64 strings, each separated by a “.” char. (See the above)
The Authorization header field in your HTTP request should look like this:
Authorization: Bearer <base64_header>.<base64_payload>.<base64_signature>
The string following “Bearer” is the value of the “access_token” member in the above JSON.
In Chilkat, you would do the following..
// This is C# code fragment, but the same applies to other programming languages using Chilkat.
Chilkat.JsonObject json = new Chilkat.JsonObject();
bool success = json.LoadFile("c:/tokens/myToken.json");
// Get the access_token member.
string accessToken = json.StringOf("access_token");
Chilkat.Http http = new Chilkat.Http();
// Setting the AuthToken property causes the "Authorization: Bearer " header to be added to each request.
http.AuthToken = accessToken;
