Invalid signature - String to sign

    I'm sorry for the delay in the response here!

    I'm happy to hear that you found the solution in a different thread.

    Shirly et al,

    It is not helpful to users who might have the same problem t say that the solution is in a differnet thread,

    without providing a link to the solution.

    Hi Ashlinga,

    I believe the poster of this thread also contacted us directly and Shirly saw that he figured out his issue separately- it's not likely that Chris' problem is identical to yours because the problem when this message is received is usually specific to the customer's code, which is most likely different to yours. If it helps, I believe Chris' issue was related to the configuration of the SDK - the cloud name, API key or API secret wasn't correct.

    If you're having trouble with your signature creation code, please take a look at this summary of how signatures are used in Cloudinary:

    And this section of the documentation specific to creating authentication signatures:

    The most likely reason you'll see this error, assuming the API secret and timestamp are correct, is that there's a mismatch between the parameters you used in your signing function and those which were sent to the server,

    The error message tells you which parameters our server was expecting to be used in the signature creation, so you can compare that to what you signed and what you send to the server, to verify your implementation is correct.

    If you're still having trouble, please create a request for our support team and include your signing code and the error you received, and we'd be happy to help
