messages endpoint parameters not working

[Ed Dow]

Greetings All,

I'm trying to use the API  to extract picture URL's from posts in my group.

From the GroupMe docs I find this:

Request GET /groups/:group_id/messages

Parameters

*before_id string — Returns messages created before the given message ID

*since_id string — Returns most recent messages created after the given message ID *after_id string — Returns messages created immediately after the given message ID

*limit integer — Number of messages returned. Default is 20. Max is 100.

Here's how I call the messages endpoint:

https://api.groupme.com/v3/groups/<groupID>/messages?token=<my_token>&limit=1

But my results are always the last 20 messages with  most recent first).

It doesn't seem like it's processing the parameters.

Any thoughts?
