If you use API’s in Business Central, probably you found some limitations in methods, depending on API to API. Sometimes you can do more, sometime less. For example, with Accounts you can use only GET method (I still don’t understand why?), and so on…
You can find details about all of them here, but I prefer to have everything on one place as it will be easier to decide if I would use standard API or eventually I need to create the custom one. Because of that, I’ve made this matrix with all standard API’s and methods you can use with them:
Except these limitations, it would be nice to know that you have some other limits as well and they are important if you want to use API’s in some solutions. Even if those limits are high, they are still limits. For example, you can have maximum 600 requests per minute in production environment and 300 in sandbox. Complete list of limits is here.
And what is also important? If you are using those API’s through Power Platform (or Logic Apps) connectors, you should understand their actions and parameters. All details can be found here, but there is a table for better understanding:
It is important to mention that all that information are subject of change.
