WordPress Article update mechanism

HI Developer : We would need your help to set up API calling form APP. (need to integrate the firebase plugin) call data to wordpress blog section only .. You can take reference on the attached JSON response format. Please note that in order to instantly update the content to both ends, App Developer will be using cloud firestore from firebase to generate real time data. The data format will be matching the JSON response attached. In the case Wordpress side is calling the APIs from us, you will need to integrate the firebase plugin. We will provide the corresponding credentials to you for further configuration. You may try with following credential. Attached also the current "preliminary dummy format" articles for your test. Thanks! *Credential*: AIzaSyCPr7vMgpxNv0P3ZurVoEqxbPV_NlyNQY4 Photo : https://gm1.ggpht.com/jGr0JX1SFIKm9qksA-ddpYz5oK0Bqjx96DWdEef6YzJ9vTjU3F_G85CsswneUa9GnRgzVOSZqaC5wZ1L5YfB5gF59jzkmoVxm8DkP_wlCIjrF5JAIIqCjVPxM7IxlrRVmpaLjpNN-moTYySwbstfbww1GbVQaMx20DBcxSoHVxWrg5vyN8SA5uUebXDioOzqiT7R6yDDfu-SHILQbX0ABSXCJQt6VO0Ux-yD8e-0joyTbl2UbNvy8URnLlTG_b5lu69JdJiPWNlERDfN8aOPui84Y9mX5a_L6Q4Nl5jPjuzurNEn_rdWgAuNHgd_KXfpnDQzlOgem9HnpkifEP6xk1xvF5F4LCSXllDGMLgz1Bz3usD_KlXnw1iJtYxlZ8sPNZEPBySrjRTLEG7wLg28L_tnZ-wczpRF7WayLcoU0PG53Ho_WkL7t9y7EDaXv5brdxwZwU6NW4gDtuycYRXpnNvnMT7yPVKkVb2RuUBFUuRZYfBYq2R-R5sodnWEWxH4PzGtjhxWrbwbZ-mJ1aIWpMD3sGtATf3-EU5rfLSByjy_Vm51YaT5MzMkDe1z9ynk9XDCIDeTVq66k3OBaGwI-Mz3URryqxBZMqdLTMmUUz-LxYeS1sXHakz4_rB1tGs1vjH0K1dvDUdMOsYEu-2XLALlGxfuy7m3jGhrNJfY6H2urd6XmBcm6Bb8tZQwMtujp1T7DKOD-X49Gs_P9y28zSuTQPJv27joeFDhYWI=s0-l75-ft-l75-ft Our Wordpress Site : Demo Site : [login to view URL] Backcend : [login to view URL] Login : demoaccount Password : dempass@word321 ** May i know what the price of help us to set up this ** (Please also suggest the way to auto-sync the articles data (if any) between two parties if our backend side is calling the APIs from your side.)
