You could handle this with Mapsly — it integrates with Odoo and lets you capture coordinates directly on the map, then sync them back into your records. That way you don’t need to build out the Google Maps API logic yourself, and you also get extras like routing, territories, and check-ins.

Mr. Yatrik , i still dont understand from that app you refer to, there is no documentation to get the position of selected places. please help. thank you

Yes, it is possible to use JavaScript API in Odoo 15 to capture coordinates when clicking on a specific place in Google Maps and then save those coordinates in fields for latitude and longitude within a record.
