Hi Benno,

Sorry for the belated answer. What worked for me, is to specify the url in the action attribute of the form, like so:

<?xml version="1.0"?>
<t t-name="payment.default_acquirer_button">
    <form action="[custom_payment_acquirer_url]" method="post" target="_self">
        <input type="hidden" name="reference" t-att-value="reference"/>
        <input type="hidden" name="amount" t-att-value="amount"/>
        <input type="hidden" name="currency" t-att-value="currency.name"/>
        <!-- submit -->
        <button type="submit" width="100px" t-att-class="submit_class">
            <img t-if="not submit_txt" src="/payment_transfer/static/src/img/transfer_icon.png"/>
            <span t-if="submit_txt"><t t-esc="submit_txt"/> <span class="fa fa-long-arrow-right"/></span>
        </button>
    </form>
</t>

Hi Henk,

I am very curious to know if you found a solution to this mystery. I have been fiddling all evening with these payment modules. All of them seem to be acting totally different from each other. Avery payment acquirer adds his own additional data to the big "payment.acquirer" table.

I will have to develop my own module, and I would greatly benefit from your experience !

form hidden inputs. if you are not able to find any documentation, i suggest you to download source code from http://nightly.odoo.com/11.0/nightly/src/odoo_11.0.latest.tar.gz and look into it. paypal, authorize etc etc.

template for authorize.net

https://github.com/odoo/odoo/blob/11.0/addons/payment_authorize/views/payment_authorize_templates.xml

code below from own payment acquirer. that works for multiple banks via single api. 2 hard-coded token + 6-12 extra tokes generated depending on bank.

<template id="custom_acquirer_button">



<t t-set="banks" t-value="tx_values.get('banks')"/>

 <t t-foreach="banks" t-as="bank">
 <div class="checkoutfi-bank">
 <form t-att-action="bank['url']" method="post">
 <input type="hidden" name="tx_url" t-att-value="bank['url']" />
 <input type="hidden" name="tx_name" t-att-value="bank['name']" />

 <t t-foreach="bank['fields']" t-as="item">
 <input type="hidden" t-att-name="item" t-att-value="item_value" />
 </t>

 <div>
 <button type="button" class="btn btn-submit">
 <div class="btn-bank">
 <img class="bank-logo" t-att-src="bank['icon']" t-att-alt="bank['name']"/>
 <span class="bank-name"><t t-esc="bank['name']" /></span>
 </div>
 </button>
 </div>
 </form>
 </div>
 </t>

</template>
