I am looking to call an internal REST API and pass the payload back in Mule 3.7.3. The request is only the URL and no body but I am getting payload errors like nullPayload.
How can I get this to work?
I am testing it with this public API https://apisandbox.openbankproject.com/obp/v2.0.0/banks
and the code I have mocked up is here:

Host should not contain a URL. It should just be the host, and HTTPS protocol specified separately. Also no need to set the payload for a GET request. updated code that works:

I am consuming one of the Google API's and provided all the OAuth 2.0 credentials in HTTP requester.I need to generate the access token, capture the token and pass this access token in the headers to get the output.But I am getting the error:
Execution of the expression "'Bearer' + payload.access_token" failed.
(org.mule.api.expression.ExpressionRuntimeException).
Is this the correct way of generating the token and accessing it?

The expression seems to be wrong.
Try value="Bearer #[payload.access_token]"
you can pass Bearer token in header as shown below : Try like this:
try this it may help you:
<http:header headerName="Authorization" value="Bearer
#[flowVars.accesstoken]"/>
i have a problem working with transform message component and mule ESB that I do not understand.
I have a simple flow that works fine, at the beginning it is Http endpoint and at the end it is Transform message component, transforms one JSON to another.
Now when I try to store payload before transform message to variable and then set payload to that variable, I get exception on transform message component:
Type mismatch
found :name, :string
required :name, :object (com.mulesoft.weave.engine.ast.dynamic.DynamicDispatchException)
com.mulesoft.weave.engine.ast.dynamic.DynamicDispatchNode:65 (null)
Here is a flow that works, and below that is the flow that doesn't work.

When i put logger to log payload before transformation, it is the same in both flows....
Can somebody tell me what am I doing wrong?
Thanks Ivan.
since the set payload is missing mime type you are getting the error use the below xml,I have tested and its working fine.<set-payload value="#[flowVars.OriginalPayload]" doc:name="Set Payload" mimeType="application/json"/>

I am facing one issue.
Requirement is I have a csv file and should transform to soap request (soap consumer component). Problem is all csv rows are transformed in one shot. In my case soap request can not handle all the rows in one request. It should be multiple call.
What I did is,

One way to accomplish this is to use a splitter and an aggregator. Your flow might look something like this:
<flow name="soapFlow1" doc:name="soapFlow1">
<file:inbound-endpoint path="E:/temp/mule" responseTimeout="10000" doc:name="File"/>
<data-mapper:transform config-ref="CSV_To_Xml_UpdateUserRequest_" doc:name="CSV To Xml<UpdateUserRequest>" />
<logger message="Converted xml is here #[payload]" level="INFO" doc:name="Logger"/>
<splitter expression="#[xpath('//item')]" doc:name="Splitter" enableCorrelation="ALLWAYS"/>
<mulexml:dom-to-xml-transformer doc:name="DOM to XML"/>
<ws:consumer config-ref="Web_Service_Consumer1" operation="UpdateUser" doc:name="Web Service Consumer"/>
<message-chunk-aggregator failOnTimeout="true" doc:name="Message Chunk Aggregator"/>
</flow>
The xpath expression obviously has to be changed to something that makes sense in your case.
I am playing with Google Task connector and ended up with following error
The content of element 'google-tasks:config-with-oauth' is not complete. One of '{"http://www.mulesoft.org/schema/mule/core":annotations, "http://www.mulesoft.org/schema/mule/google-tasks":oauth-callback-config}' is expected.
Here is my configuration
<google-tasks:config-with-oauth name="Google_Tasks"
consumerKey="sagitec.mygbiz.com"
consumerSecret="oeX9wb_GhldQJYjHKLDqC-EB" doc:name="Google Tasks"/>
<flow name="google_taskFlow1" doc:name="google_taskFlow1">

authorizationUrl="https://accounts.google.com/o/oauth2/auth"
access_type="online" force_prompt="auto" doc:name="Google Tasks"/>
<logger level="INFO" doc:name="Logger" message="#[payload]"/> </flow>
If i enter "localhost" in Domain (which is specified as optional) under Oauth tab for google-tasks:config-with-oauth, i am not getting any build error.
So my first question is, what value i have to enter under Domain and where i can get it from.
2) What is the difference between Consumer Key/Secret and ClientKey/secret.
3) in one of the sample, i saw ${google.apiKey}. What is this and if this is a variable, wgere and how to declare it.
It will be really nice if any sample provided.
Thanks in advance,
Kannan
here i added sample example for google calender authentication using google connector
your
client id >>consumerKey
client secret >> consumerSecret
${google.apiKey} >> your global google calendar config name i.e. name="Google_Calendars" in below flow

I can't spot the error: your flow looks good (except a problem I'll detail below) so, alternatively to using an http:outbound-endpoint, which can be finicky at times, you could use the http:rest-service-component.
Your next problem will be in the outputPattern of the file endpoint: remember at this point message.payload will be the response from the HTTP endpoint not the (partial) URL anymore. You need to pre-compute the file name and store it in a flow variable, then use it.
This would give:
