    I passed my exam successfully using 𝗜𝗧𝗘𝗫𝗔𝗠𝗦𝗣𝗥𝗢

     

    and around 90% of the questions were very similar to the practice material, which made the experience much easier

Hi everyone, I have this scenario: after having retrieved attachments of a case from Salesforce with Salesforce Connector I must send the content of the attachment via HTTP request. Is it possible to do this in Mulesoft Composer? If yes can you explain me how can I do it? 

 

Thanks

I have 7 integrations/flows from another platform (Unanet) into Salesforce. 6 flows work fine; 1 (higher volume and 2-part API call) frequently times out. The problem flow pattern is:

  • Authenticate
  • Get all Timesheets (endpoint1)
  • Loop1 through each Timesheet
    • Get all associated Timeslips (endpoint2)
    • Loop2 through each Timeslip (loop within a loop – bad idea?)
      • For each Timeslip, upsert into Salesforce (non-bulk upsert – bad idea?)

Is there a better pattern? Does Composer support “collections” (like Flows do) and a single bulk API call to upsert all Timeslips after collection  (i.e., in a single upsert call vs multiple upsert calls)? If not, is there a way to “re-authenticate” mid-flow? Other patterns?

    Hello @Vinod Kumar Yerra

    try to reduce the number of retrieved records / size of retrieved information, to check if that issue comes from the amount of data you are trying to query.

I'm needing to test our sandbox MuleSoft flow between our Sandbox (FC) to Sandbox (STPC) and getting the following error:

  • I've used this flow 6 months ago & it worked fine?
  • I get the error when I try to activate the flow only? (it saves just fine)
  •  Any ideas on this error? I searched thru SF help/Agent force & it was useless

    Had to place a Case with SF & they did something on their end to fix. 

    • Said "The issue that was causing the activation error was resolved by the Exchange team about an hour ago."
    • Now working as normal & can activate my flows.

I am trying to set a variable value from an incoming payload field. I am using a custom expression like upper(payload.name), but it is not working as expected.    Input Payload:    {    "name": "ben",    "age": 100  }      Current Output:    {    "resp": "PAYLOAD.NAME"  }      Issue:  The expression is being treated as a literal string rather than referencing the payload field.    Question:  How can I correctly access the incoming payload fields in MuleSoft Composer so that the name field is transformed to uppercase?

    Hi @Srinivas Pusa

     

    The expression upper(

    payload.name) is the correct syntax to convert the name field in the payload to uppercase. However, the issue occurs because MuleSoft Composer is treating the expression as a literal string instead of evaluating it.

    To fix this, make sure you enter the expression in expression mode (usually by clicking the fx button next to the input field) rather than as plain text.

     Enter the expression without enclosing it in quotes. For example, enter this exactly:

     

    upper(payload.name)

    not as "upper(payload.name)" or 'upper(payload.name)'.

    Entering the expression without quotes ensures that Composer evaluates it rather than treating it as a string literal.

    You can also use the Expression Builder or preview features to verify the output before running the app.

Hello,

 

I want to know if anybody has information on how MC could potentially integrate with BigCommerce in a two-way integration? I can't find any documentation on it and keen to learn more.

 

Thanks in advance.

    I don't have much experience using Mulesoft, but I had better luck with Skyvia. It syncs data both ways between BigCommerce and Salesforce, needs no complex setup, and has detailed documentation.

 I am currently building a workflow in MuleSoft Composer to send automated emails via Gmail. However, I am facing an issue with formatting the email body. Specifically, I am unable to insert proper line breaks or new lines in the email body text.  I have tried using \n but it does not work.

I am using mulesoft composer flow to sync data from netsuite to salesforce. There are some fields that i am unable to fetch in the flow. What are the possible reasons for that and how can i improve it?  

There are some other fields that i am able to fetch but no value is retrieved.

    Chances are that you don’t have the correct permissions to view/edit those fields in whichever system you’re connecting to.

    I would check that first.

    Is it NetSuite or Salesforce fields that are not showing up?
