Hi Florian,
Thank you for reaching out to us. I'm Partha, and I'll be assisting you today.
Based on the attached screen-print, I can observe that the parameter 'test' is being passed to the Studio REST API during execution triggering. However, it's important to note that Studio API does not include a parameter called 'test'. When creating a Studio execution with custom parameters, the value should be included in the API request as JSON data within the 'Parameters' property, as demonstrated below:
Using curl:shellCopy codecurl -X POST https://studio.twilio.com/v2/Flows/FWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Executions \--data-urlencode "To=+13105555555" \--data-urlencode "From=+12125551234" \--data-urlencode "Parameters={\"test\":\"bonjour!\",\"time\":\"8AM\"}" \-u "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:your_auth_token"For Zapier, you'll need to pass the parameter using the 'Parameters' property with a JSON payload, like this:
Property name: Parameters
Payload:{ "test": "bonjour!"}In your flow, the parameters you've passed will be accessible through a variable in the form of
{flow.data.parameter_name}. Whenever we encounter this syntax, we'll automatically replace it with the corresponding parameter's value.
For more detailed information on triggering executions with custom parameters, please refer to this resource: Trigger a Twilio Studio Flow Execution via the REST API. This documentation can provide you with a clearer understanding of the process.
If you have any further questions or need additional assistance, feel free to ask.Best,

+14Hi
Good question.
To help us have more context, please post detailed screenshots with how each of your Zap steps are configured.
thanks for your answer.
my zap launching a flow on twilio from gsheet. that work well but when receive the sms, the variable is empty :
Votre entretien d’adoucisseur aura lieu le .
1 pour confirmer
2 pour annuler
and on twilio :
+1To confirm: Zapier is correctly triggering Twilio, Twilio is sending the SMS to the correct number based on what Zapier sent (e.g. it’s not hard-coded in Twilio), but the data is not coming through?
Can you show how the target phone is set up in Twilio - assuming that part is working correctly?
I’d also re-check your variables in zapier for extra spaces or what-have-you. Maybe even create something under date called “date2” that has a hardcoded value of “Bonjour!”. Then you can test whether that comes into your SMS to try to narrow down the problem.

exactly
I tried to add “test” with “bonjour!” as value. But it doesn’t work either.
