Sendgrid-csharp: Content is still required when template is used.

[RyanONeill1970]

Sending a transactional email through the v3 API I get a bad request if I do not include content. The API documentation states that I don't need to if I have a template with content and a subject line (which I do). As I've passed the template ID I would expect a status code of 200.

I think the text content is ignored but I'm not certain. Anonymised API calls below.

Bad request:

{"from":{"email":"[email protected]"},"subject":"Hello World","personalizations":[{"to":[{"email":"r
[email protected]"}]}],"template_id":"d6a75e38-41cf-438b-904c-XXXXXXXXXXXX"}

Good request:

{"from":{"email":"[email protected]"},"subject":"Hello World","personalizations":[{"to":[{"email":"r
[email protected]"}]}],"template_id":"d6a75e38-41cf-438b-904c-XXXXXXXXXXXX","content":[{"type":"text/plain","value":"Textual content"}]}

API docs state:
If you use a template that contains content and a subject (either text or html), you do not need to specify those in the respective personalizations or message level parameters.

@RyanONeill1970 What was the error message you received?

[RyanONeill1970]

Http status code of BadRequest but no errors filled out in the error collection.

[RyanONeill1970]

Just confirmed that this error occurs when directly posting to the Send Mail API (bypassing the client).

I have also captured the exact response which is;

{"errors":[{"message":"The content parameter is required. There must be at least one defined content block. We typically suggest both text/plain and text/html blocks are included, but only one block is required.","field":"content","help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.content"}]}

I was able to reproduce and I'm now checking with our team to find out if it's a bug and if so, to put in a request for a fix.

Will not be using send grid in our service due to not being able to set it up successfully!

Hi @uknowmeright,

What version of the SDK are you using?

With the latest version, here is an example that may help.

With Best Regards,
