> PFAccountManagementLinkGameCenterAccountRequest data model.

PFAccountManagementLinkGameCenterAccountRequest data model.

## Syntax

```cpp theme={null}
typedef struct PFAccountManagementLinkGameCenterAccountRequest {  
    PFStringDictionaryEntry const* customTags;  
    uint32_t customTagsCount;  
    bool const* forceLink;  
    const char* gameCenterId;  
    const char* publicKeyUrl;  
    const char* salt;  
    const char* signature;  
    const char* timestamp;  
} PFAccountManagementLinkGameCenterAccountRequest;  
```

### Members

**`customTags`**   [PFStringDictionaryEntry](/services/playfab/api-references/c/pftypes/structs/pfstringdictionaryentry) const\*<br />*may be nullptr*

(Optional) The optional custom tags associated with the request (e.g. build number, external trace identifiers, etc.).

**`customTagsCount`**   uint32\_t

Count of customTags

**`forceLink`**   bool const\*<br />*may be nullptr*

(Optional) If another user is already linked to the account, unlink the other user and re-link. If the current user is already linked, link both accounts.

**`gameCenterId`**   const char\*<br />*is null-terminated*

Game Center identifier for the player account to be linked.

**`publicKeyUrl`**   const char\*<br />*is null-terminated*

(Optional) The URL for the public encryption key that will be used to verify the signature.

**`salt`**   const char\*<br />*is null-terminated*

(Optional) A random value used to compute the hash and keep it randomized.

**`signature`**   const char\*<br />*is null-terminated*

(Optional) The verification signature of the authentication payload.

**`timestamp`**   const char\*<br />*is null-terminated*

(Optional) The integer representation of date and time that the signature was created on. PlayFab will reject authentication signatures not within 10 minutes of the server's current time.
