Page Flow Blocks reference.

Blocks ​

HTTP Data ​

Block name: httpdata

Provides the response data returned by a Cloud Flow web hook call, HTTP POST request, or HTTP GET request when used inside a success callback.

Output ​

This block produces an output value of type Any.

Behavior ​

Returns the current HTTP response object exposed by Cloud Flow and HTTP success callbacks when available.

HTTP Error ​

Block name: httperr

Provides the error information returned by a Cloud Flow web hook call, HTTP POST request, or HTTP GET request when used inside a failure callback.

Output ​

This block produces an output value of type Any.

Behavior ​

Returns the current HTTP error object exposed by Cloud Flow and HTTP failure callbacks when available.

HTTP GET ​

Block name: httpget

Sends an HTTP GET request to the selected URL and then runs the nested success or failure statements.

Inputs ​

InputTypeDescriptionAccepts
URLstringThe target URL for the HTTP GET request. This is typically provided by a text block.text
on successstatementsThe statements to run when the HTTP GET request succeeds. Inside this block, httpdata provides the returned response data. Nested blocks run inside the generated callback for this block. customcode and customcodeexpr blocks inside this area can directly access the documented callback-scope variables.
on failurestatementsThe statements to run when the HTTP GET request fails. Inside this block, httperr provides the returned error information. Nested blocks run inside the generated callback for this block. customcode and customcodeexpr blocks inside this area can directly access the documented callback-scope variables.

Output ​

This block does not produce an output value.

Behavior ​

Generates code that sends an HTTP GET request through the ioLoop system runtime and runs the nested success or failure callbacks. The success blocks are emitted inside function(tvwaHttpData) { ... }, and the failure blocks are emitted inside function(tvwaHttpErr) { ... }, so customcode and customcodeexpr blocks inside those callbacks can access the matching in-scope variable directly.

Calls: $io.system.httpGet

Send HTTP POST ​

Block name: httppost

Sends an HTTP POST request to the selected URL and then runs the nested success or failure statements.

Inputs ​

InputTypeDescriptionAccepts
URLstringThe target URL for the HTTP POST request. This is typically provided by a text block.text
dataobjectThe data to send in the HTTP POST request. This is typically provided by a define_object block.
on successstatementsThe statements to run when the HTTP POST request succeeds. Inside this block, httpdata provides the returned response data. Nested blocks run inside the generated callback for this block. customcode and customcodeexpr blocks inside this area can directly access the documented callback-scope variables.
on failurestatementsThe statements to run when the HTTP POST request fails. Inside this block, httperr provides the returned error information. Nested blocks run inside the generated callback for this block. customcode and customcodeexpr blocks inside this area can directly access the documented callback-scope variables.

Output ​

This block does not produce an output value.

Behavior ​

Generates code that sends an HTTP POST request through the ioLoop system runtime and runs the nested success or failure callbacks. The success blocks are emitted inside function(tvwaHttpData) { ... }, and the failure blocks are emitted inside function(tvwaHttpErr) { ... }, so customcode and customcodeexpr blocks inside those callbacks can access the matching in-scope variable directly.

Calls: $io.system.httpPost
