    Hello Jotform Support Team,

    I am trying to automatically calculate the total cost of products in a submission and update a text field (input_95) with this total using the API.

    Currently, my API key (“Full Access”) does not allow me to update submission fields after submission. Is there any way to enable API access to edit text fields in existing submissions?

    This is important so the total can appear automatically in the submission, PDF, and emails.

    Thank you for your support.

    Best regards,

    Hi Bertrand,

    Thanks for reaching out to Jotform Support. Let me help you with that:

    Currently, with a "Full Access" API key, you should be able to update submission fields, including text fields, after the submission. This permission allows you to add, edit, and delete your data via the API.

    If you are unable to update the text field (input_95) in existing submissions, please ensure that your API calls are correctly formatted according to Jotform's API documentation. Also, verify that your API key indeed has "Full Access" permissions and that you are not exceeding your daily API call limits based on your subscription plan.

    Once the field is updated via the API, the total should automatically appear in the submission, PDF, and emails as you intend.

    If you need detailed guidance on how to update submission fields using the API, please let me know.

    Give it a try and let us know how it goes.

    Hi Bertrand,

    You can update the data of an existing submission field using the API with the following call:

    curl -X POST -d "submission[1_first]=Johny" -d "submission[new]=1" -d "submission[flag]=0" "https://api.jotform.com/submission/{submissionID}?apiKey={apiKey}"

    We also have a guide here that you can check out to learn more about Jotform API. Can you go ahead and try it again and let us know how it goes? If you’re still having the same issue, you can share with us the API request you are using so we can check on it.

    Reach out again if there’s anything else we can help you with.
