PATCH Request Automation API : Resource not found for the segment 'extensionUpload'

Posted on by 2,320 Moderator

Greetings Community - Having used the BC API Automation before, this is the first time I am facing a weird situation.

My goal is to publish a simple extension through automation API, following the 3 steps listed by MS here in this link. https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/itpro-introduction-to-automation-apis#upload-and-install-a-per-tenant-extension

The first part has been successful, which talks about POST : Insert Extension Upload

I am stuck in the part where through a PATCH request, the binary file is to be uploaded. I want to publish this extension to CRONUS (OOTB Company)

This gitHub discussion says that instead of {appID}, the correct parameter to pass in the URL is {packageID} from an extension metadata

My extension has not been published yet, how can I get a PackageID of an extension when it's not yet been published and moreover pass it in the PATCH request? Is there a way through powershell or something else to obtain an extensions PackageID? I see PackageID as a response when I use GET Extensions from the same BC Environment, but these are extensions already published in the environment

My request header is IF-MATCH: *

My request body is the .app file which I want to publish

FYI: Using a trial version of BC, probably has expired but not sure if it will fit this context

I have the same question (0)

    An Update for everyone reading this thread:

    I was successfully able to decode the answer to my question above, after some deep research. Here are some pointers for you:

    1. Microsoft has specified that you need 3 requests sent to the automation API for your extension to successfully load into Business Central (POST, PATCH, POST). The english names of these 3 requests is "Insert Extension Upload", "Upload Extension File" & "Install Extension"

    Of which the first request is to send a POST, which will intimate table 5447, that a new extension is now getting uploaded. From my experience, this table will have only one record at a time and the record in this table will be deleted/archived/won't bother you once you are done with all 3 steps to publish an extension via API

    The response of the first POST Request, is very important. The response contains a value named "System ID", which is nothing but your "PackageID"

    2. Use this System ID/Package ID in your upcoming/next PATCH request, in the parameter named "extensionUploadId" in 
    PATCH api.businesscentral.dynamics.com/v2.0/{environment name}/api/microsoft/automation/v2.0/companies({companyId})/extensionUpload({extensionUploadId})/extensionContent

    Now you're good to go. You now have the PackageID of the extension, even before it is published.
