is SendGrid WebApi v3 thread safe ?

[kamelsalah92]

We are creating only one instance of the SendGrid class using the API Key of each subuser we have, and the send method which make the SendGrid request can be accessed by any of the threads we have, so is this thread safe? is there any problem for using it that way ? I mean reusing the same SendGrid instance from multiple threads ?

Hello @kamelsalah92,

This library has not been tested for thread safety. I would recommend extensive testing if you wish to use the library in this way.

With Best Regards,

@kamelsalah92 The API is fully thread safe and can be used in that manner. Under the hood, we are using this HTTP connection manager. It is thread safe, however, it effectively synchronizes across threads, i.e., multiple threads cannot execute concurrently.

@thinkingserious With minimal changes, we could add the ability to handle multiple concurrent actions using this. But I'm assuming that will be a separate issue opened up.
