Robotframework POST multi object request - api

Question

I have a multi object request which look like follow in postman
{ "affordability": {
"grossIncome": 100000,
"netIncome": 80000,
"capitalRequired": 25000,
"groceries": 200,
"utilities": 300,
"savings": 400,
"services": 500,
"transport": 600,
"support": 800,
"housing": 700,
"other": 900
},
"employment": {
"sector": "CentralGovernmentSocial",
"status": "Contract",
"startDate": "2010-08-01",
"endDate": "2030-08-01"
},
"declarations": {
"debtLiability": "None",
"pendingRetrenchment": "false",
"knownMedicalCondition": "false"
},
"bank": "ABSA"
}
I am doing some automation on our API's and this one got me. I have struggled for quite some time to get the request to look like the postman request. I have managed to get that right. Though I am not entirely sure if the method I went about to solve the problem is allowing for the POST request. Cause when I run the POST request I get the below error.
HTTPError: 400 Client Error: Bad Request for url: this is a url
This is what my code looks like in:
# &{baseURL}= this is a url
# ${offer}= /offer
# ${URL}= Catenate This is a url ${appID} /offer
# log to console ${URL}
# Create Session httpbin this is a url
&{affordability}= Create Dictionary grossIncome=60000 netIncome=30000 capitalRequired=25000 groceries=500 utilities=400 savings=300 services=200 transport=100 support=100 housing=500 other=100
${affordabilityobject}= Catenate {'affordability': ${affordability}
# log to console ${affordabilityobject}
&{employment}= Create Dictionary sector=CentralGovernmentSocial status=Contract startDate=2019-08-01 endDate=2023-08-01
${employmentobject}= Catenate 'employment': ${employment}
# log to console ${employmentobject}
&{declarations}= Create Dictionary debtLiability=None pendingRetrenchment=false knownMedicalCondition=false
${declarationsobject}= Catenate 'declarations': ${declarations}
# log to console ${declarationsobject}
# &{bank}= Create Dictionary bank=FirstNationalBank
${bank}= Catenate 'bank':'FirstNationalBank'}
log to console ${bank}
${fullrequest}= Catenate SEPARATOR=, ${affordabilityobject} ${employmentobject} ${declarationsobject} ${bank}
log to console ${fullrequest}
${resp}= Post this is a url/${appID}/offer json=${fullrequest}

Answer 1

Don't use Catenate for nested dicts,
You can use Create Dictionary like this :
Then, I'm not sure, but I think you need to transform the dict to json with :
${json_string}= evaluate json.dumps(${json}) json
&{baseURL}= this is a url
${offer}= /offer
${URL}= Catenate This is a url ${appID} /offer
log to console ${URL}
Create Session httpbin this is a url
&{affordability}= Create Dictionary grossIncome=60000 netIncome=30000 capitalRequired=25000 groceries=500 utilities=400 savings=300 services=200 transport=100 support=100 housing=500 other=100
&{employment}= Create Dictionary sector=CentralGovernmentSocial status=Contract startDate=2019-08-01 endDate=2023-08-01
&{declarations}= Create Dictionary debtLiability=None pendingRetrenchment=false knownMedicalCondition=false
&{fullrequest}= Create Dictionary affordability=${affordability} employment=${employment} declarations=${declarations} bank=FirstNationalBank
log to console ${fullrequest}
${fullrequestJson}= evaluate json.dumps(${fullrequest}) json
${resp}= Post this is a url/${appID}/offer json=${fullrequestJson}
A better way to do it, is to store your json object in a separate file like "myjsonToPost.json" and you load it from file like this :
*** Settings ***
Library JSONLibrary
*** Keywords ***
&{baseURL}= this is a url
${offer}= /offer
${URL}= Catenate This is a url ${appID} /offer
log to console ${URL}
Create Session httpbin this is a url
${fullrequest} Load Json From File file_name=${EXECDIR}/path/to/myjsonToPost.json
# This method, without Library JSONLibrary
# ${fullrequestJson} evaluate json.dumps(${fullrequest}) json
# Or this one, with JSONLibrary
${fullrequestJson} Convert String To Json ${fullrequest}
${resp} Post this is a url/${appID}/offer json=${fullrequestJson}

Answer 2

Post Request Create Digital Offer
Create Session httpbin this is a url
&{affordability}= Create Dictionary grossIncome=${60000} netIncome=${30000} capitalRequired=${25000} groceries=${500} utilities=${400} savings=${300} services=${200} transport=${100} support=${100} housing=${500} other=${100}
&{employment}= Create Dictionary sector=CentralGovernmentSocial status=Contract startDate=2019-08-01 endDate=2025-08-01
&{declarations}= Create Dictionary debtLiability=None pendingRetrenchment=false knownMedicalCondition=false
&{fullrequest}= Create Dictionary affordability=${affordability} employment=${employment} declarations=${declarations} bank=ABSA
${CreateOffer_response}= Post this is a url/${appID}/offer json=${fullrequest}
Should Be Equal As Strings ${CreateOffer_response.status_code} 201
