ELI5 How to Access Business Central Web Services/API with Oauth

[@eduschimu]

Erik, the explanation with Themepark and Rollercoaster is a very good metaphor. Thanks also for the in code explanation. Very clear.

[@sarapngsinigang5129]

One of the best explanations and how to videos regarding oauth setup and consumption. Thanks Erick!

[@argusauge62]

I *LOVE* the comparison with Tivoli, Rollercoaster! Finally I understood why we need such a hell lot of fancy keys. Good Job!

[@winifix]

Thank you very much for translating Microsofts non-english instructions into plain simple examples that work!!!

[@myvisionITmanagement]

Erik, excellent! I like comparisons like this! Now I understand.

[@pain-free-it]

I was a little bit uncertain about the rollercoaster and theme park analogy at first but by the end I was fully invested! I could taste the candy floss! Also cool vintage computers in the background, I had 2 of those and other vintage stuff not in that collection... ICL OPD?

[@ghazalehghandchi1621]

Super, very good explanation and easy to use ! Thanks

[@anada1124]

Great tutorial! Perfect timing soon after BC20 no longer accepts basic authentication.

[@Hougaard]

Thanks, and yes, I have created several OAuth videos to help people transition from Basic to OAuth authentication.

[@anada1124]

@@Hougaard Using a theme park to explain OAuth2 is a very good idea. It might be even better if you also refer to Disneyland :)

[@kunalnba]

Wow! what a nightmare dude! This is really helpful; hope performance is good having to do all this stuff! We have a few heavy integrations we need to migrate to BC SaaS

[@brettmazz2607]

This video was amazing really helped to get my feet wet. Do you have any videos where you modify fa with a web service using Oauth?

[@TheJolyonSpencer]

Thank you for posting. Very good sample.

[@StevenGER92]

Thanks for this great explanation. Helps me a lot for more understanding

[@klauskaan6320]

Best ELI5 for OAuth2 anywhere!

[@JerMs2701]

Thanks a lot for your explanation. It's pretty complicated but now it became more-less understandable.

[@IvanPololi-e3x]

Top video, very good explanation and easy to use code!

[@rishichourey]

Thanks a lot Erik🤗

[@walterxfiles]

Thank you thank you very much, a good explanation, greetings from El Salvador, new follower my friend

[@lamakhaled98]

Thank you very useful explanation, how I can do that not on C# but with AL ?!

[@MladenMakreev]

Hey Erik, Thanks for the great video! Is it possible to create the Application User in Business central with an API call and not manually like you did it in the video?

[@Hougaard]

But then you'll need permission to perform that API call, isn't that an endless circle now?

[@MladenMakreev]

@@Hougaard The idea being: Log in as an admin user trough azure to business central (only once to perform the add) -> add the application user in business central trough an API call so later that application user can be used to query the data in business central. I could not find any API documentation in the Microsoft documentation for adding an Application User like the one you create in the video. Could you also point me to that?

[@yukuocheng]

Thank you for this video! It helps a lot!

[@henrikfrederiksen5863]

So SUPER! I’ll go make my theme park now❤️

[@mrdimba]

Your videos are very informative. Can you make a video for creating and updating data in business central using C#

[@stevendesilets9796]

Great explanation Thank you so much!

[@pierpaolopirovano]

Thanks a lot for your tutorial! You saved my application to stop working on 10-01 (I missed the right scope), but.... I have all working (in php) but... without add the app id in business central Azure Active Directory... why?

[@m-cos]

Excellent explanation as always, thanks again Erik! Thankfully even though Azure Active Directory Applications appears to have been renamed to Microsoft Entra Applications, typing 'aad' into the search like you did in the video still pulls it up. I tried 'azure' first and didn't find it.

[@Hougaard]

Yeah, "Entra" is now the thing :)

[@ramonmurillo167]

Thank you very much for your video. Has Microsoft changed the location of Business Central Dynamics 365 for the Azure Active Directory page? I cannot get the page to load anymore

[@Hougaard]

called Entra apps now

Hi, it is a great post. I would just like to know, how I can receive the resault without datameta or save it as csv file. Any suggestions and help would be appriciated.

[@soulfulIEM]

Erik, thanks a lot for ELI5 explanation going into OAuth 2.0. I'm wondering how and if it's possible to change Bearer's token lifetime.

[@Hougaard]

No.

[@mohdanas2846]

I am trying same but keep getting bad request for custom pages and its working for standard page.. is i am missing something i need help please

[@kennethquesada7692]

Hi Erick thanks again, is there son Inser/Post example?? regards.

[@youneselhamss2908]

Fed video, kan man gøre det uden at kode? Hvis ikke, hvor er det så du koder og hvordan connecter ide'et til det hele? Kan jeg gøre det i vscode fx?

[@Hougaard]

Hvor vil du bruge APIer fra?

[@youneselhamss2908]

With this API, I'm able to create a Get Request? We want to download some data from BC, without using dataverse, is it possible?

[@Hougaard]

Yes, what platform do you use?

[@farheen1912]

what can be other reasons that giving bad request error

[@farheen1912]

Sir I am facing a problem. I need to call 3 API on same page . I am successfully able to read first API then getting Bad request for second and third API. I tried creating new token for each API but still same error.

[@Hougaard]

Then the bad request is probably your content or query string

[@farheen1912]

@@Hougaard I found the issue. its that I was missing SUPER (Data) Permission. For Standard Pages it was working fine without SUPER (Data), but for custom pages it is required.

[@realeques]

very interesting.

[@mohammadnouritani]

It is super helpful , and if you know how to connect to business central on oauth with react or javascript that would be helpful with token login from Microsoft generation

[@Hougaard]

You should be able to take the c# example and just translate that to regular javascript

[@aymanmakhoukhi3591]

@@Hougaard Thank you so much for this tutorial, it's highly appreciated. I would love to ask you how can I use AL codeunit to consume a third party rest api and generate access token to be used on the bearer

From an API, muse the PATCH http method.
