I would like to know about any officially SDK or Library for the Adobe APIs integration. As we are facing numerous issue while implementing Adobe APIs. However, there is very less supporting tools are available online to figure out the errors.
Let us know is there any assistance for the same and your suggestion will be appreciated.
Sorry for the delay in response here. Since this is a forum for Adobe Experience Cloud SDKs, I reached out to Adobe Sign team to get answer for your query. Based on their response, there isn't SDK support for PHP.
If you have any further questions about Adobe Sign products, please post further queries on Adobe Sign forums here.
