Hi!
I am trying to use the postmark pluging but it doesn’t work at all.
it is saying:
“Postmark error: A valid API token must be provided.
…” With a lot of error below.
Would you be able to help?
Thank you
Did you by chance copy the Server API Token from the PostMark server you set up on the PostMark site and past it into the plugin page where it says “Server Key”? I just started using the plugin and it has been working pretty well. I’m not sure if the suggestion above helps, but I thought I would mention it.

Hello @laetitia.huas ,
Thank you for reaching out and for choosing our plugins. 
“Postmark error: A valid API token must be provided.
…” With a lot of error below.
Thank you for providing the screenshot. Based on the error message “PostmarkError: A valid API token must be provided” indicates that the API token is either missing or incorrect.
Would you be able to help?
I will gladly assist you, firstly verify that you have entered a valid API token from Postmark. You can find your API token in the Postmark dashboard under the API Tokens section.
If the token is missing or incorrect, update it in your Bubble application.
Lastly, ensure that the API token has the necessary permissions to perform the actions you are trying to execute.
Let us know if this was helpful, or in case you have any other plugin related questions.
Have a nice day! 
Thank you for your answer!
