--- title: "PUT /browsers" method: PUT path: "/browsers" --- # PUT /browsers `PUT /browsers` Creates a custom browser. ## Request body - object - `name` string, required — The name of the browser. The name must be unique within your account. - `description` string, password — The description of the browser. - `executionRoleArn` string — The Amazon Resource Name (ARN) of the IAM role that provides permissions for the browser to access Amazon Web Services services. - `networkConfiguration` object, required — The network configuration for a browser. This structure defines how the browser connects to the network. - `networkMode` 'PUBLIC' | 'VPC' — The network mode for the browser. This field specifies how the browser connects to the network. - `vpcConfig` object — The VPC configuration for the browser. This configuration is required when the network mode is set to VPC. - `securityGroups` SecurityGroupId[], required — The security groups associated with the VPC configuration. - `subnets` SubnetId[], required — The subnets associated with the VPC configuration. - `requireServiceS3Endpoint` boolean —

This field applies only to Agent Runtimes. It is not applicable to Browsers or Code Interpreters.

Controls whether a service-managed Amazon S3 gateway endpoint is provisioned in the VPC network topology for the agent runtime. This gateway is used by Amazon Bedrock AgentCore Runtime to download code and container images during agent startup.

Starting May 5, 2026, Amazon Bedrock AgentCore Runtime is gradually rolling out a change to how network isolation is configured for VPC mode agents. Agent runtimes created on or after this rollout will no longer include the service-managed Amazon S3 gateway. Instead, all network access, including to Amazon S3, is governed exclusively by your VPC configuration. This field cannot be set on agent runtimes created after the rollout. Passing this field in an UpdateAgentRuntime request for these agent runtimes returns a ValidationException.

Agent runtimes created before the rollout are not affected and continue to operate with the service-managed Amazon S3 gateway. To enforce full VPC network isolation on these existing agent runtimes, set this field to false via the UpdateAgentRuntime API. Before opting out, ensure your VPC provides the Amazon S3 access required for agent startup. If this field is not specified or is set to true, the service-managed Amazon S3 gateway remains provisioned.

This field is only supported in the UpdateAgentRuntime API for pre-rollout agent runtimes. Passing this field in a CreateAgentRuntime request returns a ValidationException.

- `recording` object — The recording configuration for a browser. This structure defines how browser sessions are recorded. - `enabled` boolean — Indicates whether recording is enabled for the browser. When set to true, browser sessions are recorded. - `s3Location` object — The Amazon S3 location where browser recordings are stored. This location contains the recorded browser sessions. - `bucket` string, required — The name of the Amazon S3 bucket. This bucket contains the stored data. - `prefix` string, required — The prefix for objects in the Amazon S3 bucket. This prefix is added to the object keys to organize the data. - `versionId` string — The version ID of the Amazon Amazon S3 object. If not specified, the latest version of the object is used. - `browserSigning` object — Configuration for enabling browser signing capabilities that allow agents to cryptographically identify themselves to websites using HTTP message signatures. - `enabled` boolean — Specifies whether browser signing is enabled. When enabled, the browser will cryptographically sign HTTP requests to identify itself as an AI agent to bot control vendors. - `enterprisePolicies` BrowserEnterprisePolicy[] — A list of enterprise policy files for the browser. - `location` object, required — The location of the enterprise policy file. - `s3` S3Location — The Amazon S3 location for storing data. This structure defines where in Amazon S3 data is stored. - `bucket` string, required — The name of the Amazon S3 bucket. This bucket contains the stored data. - `prefix` string, required — The prefix for objects in the Amazon S3 bucket. This prefix is added to the object keys to organize the data. - `versionId` string — The version ID of the Amazon Amazon S3 object. If not specified, the latest version of the object is used. - `type` 'MANAGED' | 'RECOMMENDED' — The type of browser enterprise policy. Available values are MANAGED and RECOMMENDED. - `certificates` Certificate[] — A list of certificates to install in the browser. - `location` object, required — The location of the certificate. - `secretsManager` object — The Amazon Web Services Secrets Manager location of the certificate. - `secretArn` string, required — The ARN of the Amazon Web Services Secrets Manager secret containing the certificate. - `clientToken` string — A unique, case-sensitive identifier to ensure that the operation completes no more than one time. If this token matches a previous request, Amazon Bedrock AgentCore ignores the request but does not return an error. - `tags` object — A map of tag keys and values to assign to the browser. Tags enable you to categorize your resources in different ways, for example, by purpose, owner, or environment. ## Response `202` Success - CreateBrowserResponse - `browserId` string, required — The unique identifier of the created browser. - `browserArn` string, required — The Amazon Resource Name (ARN) of the created browser. - `createdAt` string, date-time, required — The timestamp when the browser was created. - `status` 'CREATING' | 'CREATE_FAILED' | 'READY' | 'DELETING' | 'DELETE_FAILED' | 'DELETED', required — The current status of the browser. ## Other responses - `480` — ServiceQuotaExceededException - `481` — AccessDeniedException - `482` — ConflictException - `483` — ValidationException - `484` — ThrottlingException - `485` — InternalServerException --- [API](https://skmtc.net/aws/apis/bedrock-agentcore-control.md) · [All operations](https://skmtc.net/aws/apis/bedrock-agentcore-control/llms.txt) · [OpenAPI document](https://skmtc-service-staging.skmtc.workers.dev/v1/apis/aws/bedrock-agentcore-control/versions/0ebde766792b/schema)
