N/A"

/Expression

Specify the service endpoint URL of REST API. You can provide the URL in one of the following ways:

As a JavaScript expression in the expression language.

For example: http://coresnapsqa-v4.s3.us-east-2.amazonaws.com/S3Account/'+encodeURIComponent("Special_char_owner_!3)12.json")

As a plain string that you should enclose in double quotes ("").

For example: "https://www.example.com/slm/webservice/v2.0/defect/%s".replace("%s", $.widg et.id)

For Snaps using AWS Signature V4 accounts, you can use the canonical name (CNAME) for the URI, so it's not necessary for the URL to end with amazonaws.com or have the region and service provided in it. However, if you are using the CNAME, you must provide it in the AWS Region and Service Name fields in the AWS Signature V4 account.

The hostname in the CNAME must be equal to the bucket name.

For example:
Previous URI: https://jsmith-bucket.nia3.snaplogic.net.s3.us-west-1.amazonaws.com/HttpClientTest/test1

New URI with CNAME: https://jsmith-sltest.nia3.snaplogic.net/HttpClientTest/test1

Here, the bucket name is jsmith-bucket.nia3.snaplogic.net

The Snap finds the value at the JSON path $.widget.id in the input data and replaces "%s" in the Service URL with the value. You can connect File Reader and JSON Parser Snaps upstream of a REST Put Snap and prepare the following JSON file for the File Reader Snap:

Note

The Service URL for the REST snap has to be valid. If the Service URL contains any special characters, such as !, =, %21, $, and ^, the Snap throws an exception error. You can escape the special characters (using expression language) using one of the following methods:

Use the global function encodeURIComponent on any variables that might contain special characters so that they are encoded properly. For example, 'http://coresnapsqa-v4.s3.us-east-2.amazonaws.com/S3Account/'+encodeURIComponent(_fileName)
If you are aware of the code, use the code directly in the Service URL field. For example, http://coresnapsqa-v4.s3.us-east-2.amazonaws.com/S3Account/Special_char_owner_%213%2912.json; where <%213%2912> is the code.

We recommend you use the former (encodeURIComponent) method to escape the special characters.

Default Value: N/A
Example: https://www.example.com/slm/webservice/v2.0/defect/%s".replace("%s", $.widget.id)

HTTP entity

String/Expression

Checkbox

Multiexcerpt macro

name	Show_All_Headers

The REST endpoint may return a response with multiple headers with the same header name.

If this property is deselected, only one response header will be shown in the output document.
If selected, the response header displays all the response header values received as a list of objects.

If any of these objects has a key-value format, it is parsed into the map data.

Response entity type

String

Select one of the following response entity types you want the Snap to display in the output document.:

DEFAULT - Select this option to enable the Snap to process the response automatically. The response entity is processed automatically based on the Content-Type header in the response. If the content provided does not parse with the provided Content-Type, the snap will result in an error.
The following two scenarios describe the Snap’s behavior when using the Process Array checkbox::
- When you select the Process Array checkbox, the Snap parses JSON or XML and produces a stream of documents at the output view.
- When you deselect the Process Array checkbox, the Snaps sends the data as it is at the output view.
TEXT - Select this option to enable, the Snap to produce an entity of string type.
BINARY - Select this option to enable the Snap to produce an entity of byte array type.

Info
If you select TEXT or BINARY, the Snap does not parse the entity content. If you select DEFAULT, the Snap produces the expected result in most cases, but if it fails to process as expected, you can set the Response entity type to TEXT or BINARY.

Default Value: DEFAULT
Example: TEXT

Cookie Policy

Dropdown list

Multiexcerpt macro

name	Cookie Policy

Select a Cookie Policy from the following options:

Browser Compatibility: This policy is compatible with different servers even if they are not completely standards-compliant. If you are facing issues while parsing cookies, you should try using this policy.
Ignore Cookies: This cookie policy ignores all cookies. You should use this policy to prevent HTTP Client from accepting and sending cookies.
RFC Strict: This policy uses the set-cookie header
RFC Lax: The policy uses set-cookie and set-cookie2 for parsing.

When using a cookie policy, you must select Show All Headers checkbox to view the parsed cookies from the cookie policy specification.

Default Value: Ignore Cookies

Example: RFC Strict

URL Parse Exception - 403

The Service URL path might be containing any of the following special characters: !, =, %, #, $, ^&()_¢äâêîôûñç¡¿ÉÙËÇ¨°¸ðø©¢¾A+²½µ®§÷¶þ

To escape the special characters, use the global function encodeURIComponent on any variables that might contain special characters so that they are encoded properly.

Too many Requests - 429

There are too many requests to REST endpoint.

Wait for the retry to succeed.

Rest related Snaps extract the response header and automatically retry when they encounter status 429.

By default, the retry interval (Retry-After) is specified in the HTTP response header.

Examples

If no value is available for Retry-After, then the Snap’s Retry Interval value is used.
