Docs Connect Components Processors http http Available in: Self-Managed Performs an HTTP request using a message batch as the request body, and replaces the original message parts with the body of the response. Common Advanced # Common config fields, showing default values label: "" http: url: "" # No default (required) verb: POST headers: {} rate_limit: "" # No default (optional) timeout: 5s parallel: false # All config fields, showing default values label: "" http: url: "" # No default (required) verb: POST headers: {} metadata: include_prefixes: [] include_patterns: [] dump_request_log_level: "" oauth: enabled: false consumer_key: "" consumer_secret: "" access_token: "" access_token_secret: "" oauth2: enabled: false client_key: "" client_secret: "" token_url: "" scopes: [] endpoint_params: {} basic_auth: enabled: false username: "" password: "" jwt: enabled: false private_key_file: "" signing_method: "" claims: {} headers: {} tls: enabled: false skip_cert_verify: false enable_renegotiation: false root_cas: "" root_cas_file: "" client_certs: [] extract_headers: include_prefixes: [] include_patterns: [] rate_limit: "" # No default (optional) timeout: 5s retry_period: 1s max_retry_backoff: 300s retries: 3 backoff_on: - 429 drop_on: [] successful_on: [] proxy_url: "" # No default (optional) batch_as_multipart: false parallel: false The rate_limit field can be used to specify a rate limit resource to cap the rate of requests across all parallel components service wide. The URL and header values of this type can be dynamically set using function interpolations described here. In order to map or encode the payload to a specific request body, and map the response back into the original payload instead of replacing it entirely, you can use the branch processor. Response codes Redpanda Connect considers any response code between 200 and 299 inclusive to indicate a successful response, you can add more success status codes with the field successful_on. When a request returns a response code within the backoff_on field it will be retried after increasing intervals. When a request returns a response code within the drop_on field it will not be reattempted and is immediately considered a failed request. Add metadata If the request returns an error response code this processor sets a metadata field http_status_code on the resulting message. Use the field extract_headers to specify rules for which other headers should be copied into the resulting message from the response. Error handling When all retry attempts for a message are exhausted the processor cancels the attempt. These failed messages will continue through the pipeline unchanged, but can be dropped or placed in a dead letter queue according to your config, you can read about these patterns. Examples Branched Request This example uses a branch processor to strip the request message into an empty body, grab an HTTP payload, and place the result back into the original message at the path repo.status: pipeline: processors: - branch: request_map: 'root = ""' processors: - http: url: https://hub.docker.com/v2/repositories/jeffail/benthos verb: GET headers: Content-Type: application/json result_map: 'root.repo.status = this' Fields url The URL to connect to.

Type: bool Default: false Requires version 3.45.0 or newer tls.root_cas An optional root certificate authority to use. This is a string, representing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.
