Signature

Each request must be signed for validation. Clients will be given secret keys for different documentations. The key will be processed to provide signature through these following steps:

Parameters used:

• Request UUID
• Request Datetime
• Community Code
• Key
• Service Name

Step 1 :

Combine the parameters used in the following order:

##Request UUID##Request Datetime##Community Code##Key##Service Name ##

Example :

Request UUID : 123ABC-DEF456
Request Datetime : 2017-08-08 09:17:45
Community Code : MYCOMMCODE
Key : S3cr317kEY
Service Name : SendInvoice

This will be converted into a string as shown below:

Result = ##123ABC-DEF456##2017-08-08 09:17:45##MYCOMMCODE##S3cr317kEY##SendInvoice##

Step 2 :

Uppercase parameter combination in Step 1:

##123ABC-DEF456##2017-08-08 09:17:45##MYCOMMCODE##S3CR317KEY##SENDINVOICE##

Step 3 :

Hash the result of Step 2 by using sha256:

$sha256 = hash(sha256, '##123ABC-DEF456##2017-08-08 09:17:45##MYCOMMCODE##S3CR317KEY##SENDINVOICE##')

Result = 638f5fd9f590ce81b15570d32edaec03dab1498aa2525947411be6d6e2aa7a2d

The result of step 3 will be used as the value of the signature parameter.
