咨询Yammer API获取全公司群组消息的正确请求格式及示例

I’ve run into this exact issue before—using 0 as the group ID for the All Company group doesn’t work because Yammer doesn’t actually use 0 as a valid ID for that group. Here’s how to correctly pull those messages:

Option 1: Use the Actual All Company Group ID #

First, you need to retrieve the real group ID for your network’s All Company group:

• Send a GET request to:

  https://www.yammer.com/api/v1/groups.json?network_id=Default
  

• In the JSON response, look for the group with the name All Company (or your network’s localized equivalent, like "全公司" for Chinese). Grab the id value from that entry—it’ll be a positive integer, similar to the 118******* ID you used for your other group.

Once you have that ID, construct your request just like you did for the specific group:

https://www.yammer.com/api/v1/messages/in_group/{ALL_COMPANY_GROUP_ID}.json?network_id=Default&newer_than=408119030538240

Replace {ALL_COMPANY_GROUP_ID} with the actual ID you pulled from the groups endpoint. This will return the same structured JSON response you get from your working group request.

Option 2: Use the Company Feed Endpoint (No Group ID Needed) #

If you don’t want to fetch the group ID first, Yammer has a dedicated parameter to pull the company-wide feed directly:

• Send a GET request to:

  https://www.yammer.com/api/v1/messages.json?feed_type=company&network_id=Default&newer_than=408119030538240
  

The feed_type=company parameter tells the API to return all messages visible across your entire network, which is exactly what the All Company group includes.

Why 0 Doesn’t Work #

Yammer assigns unique positive integer IDs to all groups, including the All Company group. 0 isn’t a valid group ID in their system, so the API doesn’t recognize that request and throws an error instead of returning the expected messages.
