# Get the key
Joining an organization requires a key, which ensures that people who are not invited cannot join the organization.
Therefore, to invite members to join the organization, the first step is to obtain this key. After obtaining the key, you can:
+ Splice the key to the invitation address, and the user can join the organization with the key after clicking;
+ Write the key into the QR code and let users scan the code to join the organization;
```javascript
WXAPI.organizeJoinKey({
token: '000'
})
```
+ token current user login credentials
+ organizeId organization ID
+ minutes expiration time (how many minutes), if not passed, the default is 10 minutes
+ renew true: Each time a new key is obtained, the old key is invalidated. This is the default method; false: If there is a key before, return the last key, otherwise obtain a new key.
# Join the organization
```javascript
WXAPI.organizeJoin({
token: '000',
joinKey: 'Key obtained in the previous step'
})
```
+ token current user login credentials
+ joinKey The secret key to join the organization
