# PutRolePolicy
<a name="API_PutRolePolicy"></a>

Adds or updates an inline policy document that is embedded in the specified IAM role.

When you embed an inline policy in a role, the inline policy is used as part of the role's access (permissions) policy. The role's trust policy is created at the same time as the role, using [https://docs.amazonaws.cn/IAM/latest/APIReference/API_CreateRole.html](https://docs.amazonaws.cn/IAM/latest/APIReference/API_CreateRole.html). You can update a role's trust policy using [https://docs.amazonaws.cn/IAM/latest/APIReference/API_UpdateAssumeRolePolicy.html](https://docs.amazonaws.cn/IAM/latest/APIReference/API_UpdateAssumeRolePolicy.html). For more information about roles, see [IAM roles](https://docs.amazonaws.cn/IAM/latest/UserGuide/roles-toplevel.html) in the *IAM User Guide*.

A role can also have a managed policy attached to it. To attach a managed policy to a role, use [https://docs.amazonaws.cn/IAM/latest/APIReference/API_AttachRolePolicy.html](https://docs.amazonaws.cn/IAM/latest/APIReference/API_AttachRolePolicy.html). To create a new managed policy, use [https://docs.amazonaws.cn/IAM/latest/APIReference/API_CreatePolicy.html](https://docs.amazonaws.cn/IAM/latest/APIReference/API_CreatePolicy.html). For information about policies, see [Managed policies and inline policies](https://docs.amazonaws.cn/IAM/latest/UserGuide/policies-managed-vs-inline.html) in the *IAM User Guide*.

For information about the maximum number of inline policies that you can embed with a role, see [IAM and Amazon STS quotas](https://docs.amazonaws.cn/IAM/latest/UserGuide/reference_iam-quotas.html) in the *IAM User Guide*.

**Note**  
Because policy documents can be large, you should use POST rather than GET when calling `PutRolePolicy`. For general information about using the Query API with IAM, see [Making query requests](https://docs.amazonaws.cn/IAM/latest/UserGuide/IAM_UsingQueryAPI.html) in the *IAM User Guide*.
