Hello everyone,

I wanted to know what the suggested method to integrate AEM with Box.com would be. Box is a cloud storage solution.

The use case would be to use AEM Forms as the front end to capture information and generate a PDF upon form submission. Once submitted, the PDF will also be sent from AEM to Box to be stored.

Box provides an API reference, but I am not sure how to start to create this integration with AEM.

Hi @techddx,

As a first step, decide on the authentication method. I suggest to read through the entire links under Authentication section and decide based on your project's Box account set up.

https://developer.box.com/guides/authentication/

Once when we are authenticated, we can make use of the desired APIs

Note : Can make use of Apache commons Http client or jersey client or any related for all the API calls.

For your use case to upload files to Box account,

Can make use of Server side authentication using JWT - No user interaction, token defaults to Box's service account.
More details about available authentication methods : https://developer.box.com/guides/authentication/select/
Use the access token obtained in previous step to make API calls.
Example : For uploading a file - https://developer.box.com/reference/post-files-content/ Request details in right hand section has sample snippet for few select languages.

Please check and let know if you are looking for any specific information in the flow.

Hi @vijayalakshmi_s, thank you for this information.

I have created a Box Application to use the Server Side Authentication with JWT to authenticate to the Box API. The current plan is to submit the adaptive form to a custom workflow process that calls the Box API. As per: https://experienceleague.adobe.com/docs/experience-manager-learn/forms/adaptive-forms/custom-process-step-aem-workflow.html?lang=en#adaptive-forms

However, I am encountering an issue when calling the Box API from within the AEM workflow. I have installed the required dependencies of the Box SDK as an OSGi bundle, but I am not sure how to resolve this issue. I will attach a snippet of the error log.
