You could use something like this(this is an api test model that I create):

from openerp.osv import fields, osv
import requests

class solt_http_test(osv.osv):
    _name = 'solt.http.test'
    
    _columns = {
        'name': fields.char('URL', size=1024),
        'method': fields.selection([('post', 'POST'), ('get', 'GET'), ('put', 'PUT'), ('patch', 'PATCH'), ('delete', 'DELETE')], string='HTTP Method'),
        'user': fields.char('User', size=64),
        'password': fields.char('Password', size=64),
        'content': fields.text('Content'),
        'response': fields.text('Response'),
    }
    
    def action_request(self, cr, uid, ids, context=None):
        for test in self.browse(cr, uid, ids,context):
            auth = None
            if test.user and test.password:
                auth = (test.user,test.password)
            headers = {'Content-Type': 'application/json', 'Accept': 'application/json'}
            result = getattr(requests, test.method)(test.name, test.content, auth=auth, headers=headers)
            test.write({'response':result.text})
        return True
solt_http_test()

Modify this for your convenience. Here is the views, action and menu i use:

        <record id="solt_http_test_form_view" model="ir.ui.view">
            <field name="name">solt.http.test.form</field>
            <field name="model">solt.http.test</field>
            <field name="arch" type="xml">
                <form string="HTTP Test" version="7.0">
                    <header>
                        <button name="action_request" string="Test" type="object" icon="gtk-go-forward"/>
                    </header>
                    <sheet layout="auto">
                        <group colspan="6">
                            <field name="name"/>
                            <field name="method"/>
                            <field name="user"/>
                            <field name="password"/>
                        </group>
                        <group>
                            <field name="content"/>
                        </group>
                        <group>
                            <field name="response"/>
                        </group>
                    </sheet>
                </form>
            </field>
        </record>

                </tree>
