Invalid Hash When Initiating a RemoteTransaction

#7

I have resolved the error on my end. A few pointers. It is expected that the last key-value pair in your request is the hash. Everything above it is used in generating the hash. In your case the steps would look like this

Step 1
method:ecocash
phone:0771111111
id:xxxx
reference:TEST REF
amount:99.99
returnurl:http://www.google.com/search?q=returnurl
resulturl:http://www.google.com/search?q=resulturl
authemail:someone@sommail.com
status:Message

step 2 concatenate values as a string (note keys are not included)
ecocash0771111111xxxxTEST REF99.99http://www.google.com/search?q=returnurlhttp://www.google.com/search?q=resulturlsomeone@sommail.comMessage

step 3 append integration key
ecocash0771111111xxxxTEST REF99.99http://www.google.com/search?q=returnurlhttp://www.google.com/search?q=resulturlsomeone@sommail.comMessage[intergration key]

step 4 - sha512 hash

Thank you Harvey. I have done what you said but still no joy on my side… Same Error

#9

I hope you did not give up on me @Harvey:sweat_smile: . I am still stuck.

Hi there no I have not. I have been trying to figure out a way to share testing info , so far I am looking at Postman’s "share " feature. As a side note why are you not using the SDK’s?

#11

While generating the hash, the order of concatenation of the values matters.
So when generating the hash for initiating mobile money transactions, the order should be:

[Integration ID]TEST REF99.99http://www.google.com/search?q=returnurlhttp://www.google.com/search?q=resulturlsomeone@sommail.comMessageecocash0771111111[Integration Key]

Continuing the discussion from Invalid Hash When Initiating a RemoteTransaction:

Thank you very much @Harvey… Without getting into details i will just say that my hands are tied, project constraints, therefore i can’t use any of the SDK’s.

I will be patiently waiting for your help.

That’s a sign of victory… Thanks Harvey… Works like a charm in postman.

I love your persistence @Harvey … :raised_hands:

#17

@Harvey … Kindly explain what was wrong with my initial implementation. My goal is that i want to submit the request using Ajax post so i might also be haunted by my previous errors. How best can i perform an ajax post? Regards

Postman has a feature to generate code , just under the save button there is a “code” button
