# Updating the Image Sharing Status

#### Scenario

The status of a shared image can be updated after the tenant accepts or rejects the image.

The token obtained from IAM is valid for only 24 hours. If you want to use a token for authentication, you can cache it to avoid frequently calling the IAM API.

#### Involved APIs

If you use a token for authentication, you must obtain the token and add X-Auth-Token to the request header of the IMS API when making an API call.

- IAM API used to obtain the token

  URI format: POST https://IAM endpoint/v3/auth/tokens

- IMS API used to update the image sharing status (Native OpenStack API)

  URI format: PUT https://IMS endpoint/v2/images/Image ID/members/Member ID

#### Procedure

1. Obtain the token.
2. Send PUT https://IMS endpoint/v2/images/Image ID/members/Member ID. Member ID indicates the project ID of the image recipient.
3. Add X-Auth-Token to the request header.
4. Specify the following parameters in the request body:

       {
           "status": "accepted"  //accepted indicates that the shared image will be accepted.
       }

5. Check the response parameters.

       {
           "status": "accepted",  //Sharing status (accepted indicates that the shared image will be accepted.)
           "created_at": "2016-09-01T02:05:14Z",  //Time when the image is shared
           "updated_at": "2016-09-01T02:37:11Z",  //Time when the image is updated
           "image_id": "d164b5df-1bc3-4c3f-893e-3e471fd16e64",  //Image ID
           "member_id": "edc89b490d7d4392898e19b2deb34797"  //Member ID (that is, project ID of the image recipient)
           "schema": "/v2/schemas/member"  //Image sharing schema
       }
