Good morning:
I think you can achieve that by doing the following tasks:
1. Define a Simple Input Contract with two input data in the schema: both strings, one for the tel and the other for the hash_key.
The JSON representation of the Input Contract should be like this one:
{
"type": "object",
"required": [
"tel",
"hashKey"
],
"properties": {
"tel": {
"type": "string"
},
"hashKey": {
"type": "string"
}
},
"additionalProperties": true
}
2. Then, you can define a request Body Template like the following:
{"tel": "${input.tel}", "hash_key": "${input.hashKey}"}
3. Finally, please put your input data in the Test option and try it again.
I expect that helps to you.
