Client Id and Client Secret.• The Client Id and Client Secret will be used to get an access

AutoComplete: 10 requests in 10 seconds. Messages: 10 requests in 30 seconds. Notifications: 10 requests in 30 seconds. All Other Resources: 10 requests in 10 seconds.

• Exceeding any rate limits will result in all endpoints returning a status code of 429 (Too Many Requests).

Open GraphConnects activities together with a common Open Graph object.

An activity takes the format:<Actor> <Action> <Object> on <App Name>: <Message>

“John Doe” created “Sales Contract” on Contract Meow: Signed a new client!

More info at: https://developer.yammer.com/opengraph/

ActivitiesUse Open Graph Object Format<Actor> <Action> <Object> on <App Name>: <Message>Actor - The actor is the user that performed an action. Action - The action is a verb that describes what happened to the object.

Standard actions are “created, updated, deleted, followed, and liked”.

Custom Actions can be created for your network.Object - An OG object represents an entity instance in your application, like a particular Contract or Event (Lunch Meeting). URL is the unique identifier.

Activity Example (JSON OG representation)

{"activity":{

"actor":{"name":"John Doe","email":"john@contract-meow.com"},"action":"create",

"object": {"url":"https://www.contract-meow.com/34242","title":"Sales Contract"},

"message":"Signed a new client! ""users":[

{"name":"Jane Doe","email":"jane@contract-meow.com"}

]}
