I apologize for the very late reply.
I have worked very hard over the past month to develop Bubble. As a result, I have a good understanding of the native features of Bubble and can create simple web applications without hesitation.
On the other hand, API connections are still in the process of being mastered. Actually, I was struggling with the API connector implementation. One of the problem was that I could not debug the internal logic, then did not know if I was getting the API token correctly.
However, A month ago I did not fully understand the solution you gave me. How foolish I was. I understood now because I have experienced failure.
So if I do it this way, I can directly check the api token. wonderful!
Such an elegant implementation had never occurred to me.
Now, The bubble app I’m building will be built-into a native app (iOS/Android) developed with traditional programming. After consulting with our iOS/Android developers, we’ve come to the conclusion that use “Client Credentials Grant”.
The method you described was “User-Agent Flow”, and I expect this can be applied to “Client Credentials Grant” as well.
I sincerely appreciate your detailed explanation. Thank you so much.
