Package: satispaython
satispaythonA simple library to manage Satispay payments following theWeb-button flow.Requirementscryptography>= 3.3httpx>= 0.16InstallationYou can install this package with pip:pip install satispaython.UsageType hints are available for all public functions.Key generationFirst of all you need a RSA private key. You may generate the key by yourself or you may use the provided utility functions:fromsatispaython.utils.utilsimportgenerate_key,write_key# Generate a keyrsa_key=generate_key()# Write the key into a filewrite_key(rsa_key,'path/to/file.pem')# You can also generate a key and save it directly to a provided pathrsa_key=generate_key('path/to/file.pem')In order to load the key from a PEM encoded file you may use the utility function:fromsatispaython.utils.utilsimportload_keyrsa_key=load_key('path/to/file.pem'):information_source: The functionwrite_keystores the key in the PEM format. If you generate the key with any other method and you would like to use theload_keyfunction, please make sure the key is stored within a file in the PEM format.:information_source: Satispaython key management is based oncryptographyso all the functions which require an RSA key parameter expect an object of the classRSAPrivateKey. If you don't use theload_keyfunction then make sure your key is an instance ofRSAPrivateKey.You may protect your key with a password simply adding thepasswordparameter:write_key(rsa_key,'path/to/file.pem','mypassword')rsa_key=load_key('path/to/file.pem','mypassword')rsa_key=generate_key('path/to/file.pem','mypassword')Both functions acceptPathLikeobjects:frompathlibimportPathpath=Path('path/to/file.pem')rsa_key=generate_key(path,'mypassword')write_key(rsa_key,path,'mypassword')rsa_key=load_key(path,'mypassword')Satispay APISatispaython web requests are based onhttpxso the following functions return an instance ofResponse. On success, the Satispay API responds with a JSON encoded body, so you can simply check for theresponse.status_codeand eventually get the content withresponse.json().:information_source: If you need to use the Sandbox endpoints be sure to read theproper section.In order to use theSatispay APIsimply import satispaython:importsatispaythonThen you can:Obtain a key-id using a tokenresponse=satispaython.obtain_key_id(token,rsa_key):information_source: The token is the activation code that can be generated from the Satispay Dashboard (or provided manually for Sandbox account).:warning: Tokens are disposable! The key-id should be saved right after its creation.Make an authentication testresponse=satispaython.test_authentication(key_id,rsa_key):information_source: Authentication tests work on Sandbox endpoints only.Create a paymentresponse=satispaython.create_payment(key_id,rsa_key,amount_unit,currency,body_params=None,headers=None)You may use the utility functionformat_datetimeto get a correctly formattedexpiration_dateto supply to the request:fromdatetimeimportdatetime,timezone,timedeltafromsatispaython.utils.utilsimportformat_datetimeexpiration_date=datetime.now(timezone.utc)+timedelta(hours=1)expiration_date=format_datetime(expiration_date)Get payment detailsresponse=satispaythonsatispaython.get_payment_details(key_id,rsa_key,payment_id,headers=None)Sandbox endpointsBy default satispaython points to the production Satispay API. If you need to use theSandboxendpoints, simply set thestagingparameter toTrue:response=satispaython.obtain_key_id(rsa_key,token,staging=True)response=satispaython.create_payment(key_id,rsa_key,amount_unit,currency,body_params=None,headers=None,staging=True)response=satispaython.get_payment_details(key_id,rsa_key,payment_id,headers=None,staging=True)Clients, AsyncClients and AuthSatispaython offers specialized versions ofhttpx'sClient,AsyncClientandAuthclasses:fromsatispaythonimportSatispayClientwithSatispayClient(key_id,rsa_key,staging=True)asclient:response=client.create_payment(amount_unit,currency,body_params=None,headers=None)response=client.get_payment_details(payment_id,headers=None)fromsatispaythonimportAsyncSatispayClientasyncwithAsyncSatispayClient(key_id,rsa_key,staging=True)asclient:response=awaitclient.create_payment(amount_unit,currency,body_params=None,headers=None)response=awaitclient.get_payment_details(payment_id,headers=None)importhttpxfromsatispaythonimportSatispayAuthauth=SatispayAuth(key_id,rsa_key)url='https://staging.authservices.satispay.com/wally-services/protocol/tests/signature'response=httpx.post(url,auth=auth)
