URL Adapter Reference

This page explains the URL Adapter in Bridge context. If you were looking for the same information regarding the PAS Designer, refer to URL Adapter in the Designer guide.

All URL adapter parameters, that are specified on the <<URLAlias>> in the component diagram, can also be supplied dynamically via action script. Find below a list of all relevant parameters of the URL adapter and their description.

With the URL adapter, it is possible to get and put messages via file transfer protocols: FTP, FTPS and SFTP. These protocols often get confused and mixed up due to the similarity in function and names. Please refer to Using the URL Adapter with the FTP Protocol and Related Protocols for a distinction and more information on the usage with the URL adapter.

Advanced
Follow Redirects (followRedirects)	The maximum number of redirects to follow.	any positive integer or 0
Ignore Http Errors (ignoreHttpErrors)	If true, HTTP error codes > 300 will not cause an exception in the model. This implies, that the response body is accessible even if HTTP errors occur. The default value is false.	true	Ignore HTTP error codes > 300.
Ignore Http Errors (ignoreHttpErrors)		false	Do not ignore HTTP errors (default).
Options (options)	Native cURL options as listed on Setting cURL Options on the URL Adapter . Use one of the following syntax rules: values separated by `','` in one line values separated by `' '` in one line list of tagged values	valid cURL options, e.g. `CURLOPT_TIMEOUT=20`
Request Http Header Roles (requestHttpHeaderRoles)	Builder 7.12.0 Runtime 2020.12 In the context of HTTP based adapters (URL, REST, SOAP), enable automatic header generation for the listed headers. These definitions overwrite the default behavior, and X-Transaction-Id, X-Request-Id, X-Sender-Host and/or X-Sender-Service will be substituted by this definition. requestHttpHeaderRoles can hold a list of definitions in format `<http header name>:<role>`, that will automatically be generated for each adapter call on this alias. `<role>` can be one of the listed allowed values (one list entry per line). Refer to HTTP Header Support > Overwriting the Standard HTTP Headers for more details on header roles.	client_host	Provide the client host in a header `<http header name>` instead of X-Sender-Host.
		client_service	Provide the client service in a header `<http header name>` instead of X-Sender-Service.
		correlation_id	Provide the correlation ID in a header `<http header name>` instead of X-Request-Id.
		transaction_id	Provide the transaction ID in a header `<http header name>` instead of X-Transaction-Id.
		passthrough	Pass a present header `<http header name>` to the called service.
		passthrough=`<request header name>`	Pass an incoming header `<request header name>` to the called service under the name of `<http header name>`. This is equivalent to renaming a header.
Dig est Algorithm (digestAlgorithm)	Builder 7.12.0 Runtime 2021.1 Generates a HTTP digest header using the specified algorithm. When applied, a digest header is generated using the specified algorithm, and sent with the request . The generated header conforms with RFC3230 and RFC5843. Only one value is supported (no multi-value header).	None	No header generated.

Since Runtime 2022.6 the Runtime uses Transfer-encoding: chunked for POST requests. You can override this behavior by setting

Transfer-Encoding: <empty string>
Content-Length: <length of the body>"
