ruby - How do I insert X-PAYPAL headers with Rails Invoice SDK? -

i'm using paypal sdk invoicing located here: https://github.com/paypal/invoice-sdk-ruby

this works great.

i integrated paypal permissions sdk rails: https://github.com/paypal/permissions-sdk-ruby

the authorization workflow working great.

so need put them together. documentation permissions sdk leaves off after token. doesn't explain how use other paypal sdks (at least not understand :d ) invoice sdk tells see auth sdk.

paypal tells me:

# third-party auth headers -h "x-paypal-security-subject:<receiveredress>"  # merchant's paypal e-mail -h "x-paypal-authentication:<oauthsig>"          # generated oauth signature 

don't know how insert that. request generated here in model:

    @create_and_send_invoice = api.build_create_and_send_invoice(paypalized || default_api_value) 

the data assembled in invoice model so:

paypalized = { :access_token => self.user.paypal_token,  :invoice => {   :merchantemail => self.user.paypal_email || self.user.email,   :payeremail => self.client.email,   :itemlist => @itemlist,   :currencycode => "usd",   :paymentterms => "dueonreceipt",   :invoicedate => self.updated_at,   :number => self.name,   :note => self.description,   :merchantinfo => @businessinfo   # project / invoice title?  } # end invoice } # end paypalized return paypalized 

this implementation not working , access_token field being rejected. looked through gems associated sdks can't see headers built or how interact that.

update: found gives me clue...

       invoice_http_header = { "x-paypal-request-source" => "invoice-ruby-sdk-#{version}" } 

this seems used here during calls in paypal-sdk-invoice gem:

    # service call: createandsendinvoice   # @param createandsendinvoicerequest   # @return createandsendinvoiceresponse   def createandsendinvoice(options = {} , http_header = {})     request_object  = buildcreateandsendinvoice(options)     request_hash    = request_object.to_hash     ... 

i notice there's 2 arguments: options , http_header. it's possible can modify http_header argument , pass way in controller:

@create_and_send_invoice_response = api.create_and_send_invoice(@create_and_send_invoice, @cutsom_header) 

or maybe

@create_and_send_invoice = api.build_create_and_send_invoice(data, custom_header) 

i'll keep updated since googled around lot , couldn't find clear answers on how this...

you have pass token , token_secret while creating api object third-party authentication.

@api = paypal::sdk::invoice::api.new({    :token => "replace token",    :token_secret => "replace token-secret" })
