Overview

Building an app for monday.com? This guide walks you through the complete development process, from initial concept to marketplace launch. Whether you're creating your first integration or expanding your existing app's capabilities, follow this structured approach to ensure success.

Your monday app development journey consists of four distinct phases, each with specific goals:

Phase 1: App Definition

Goal: Define what you're building and why it matters to users

In this phase, you'll identify the specific problem your app solves and how it creates value for monday.com users. The most successful apps integrate seamlessly into existing workflows and are part of a broader solution, rather than standalone tools.

Market Research

User Needs Assessment:

• What gaps exist between monday.com and your product?
• Which shared use cases would benefit from integration?
• How do users currently handle these workflows manually? Competition Analysis:
• What similar apps already exist in the marketplace?
• How can your app differentiate itself?
• What features are users requesting that aren't currently available?

Value Proposition

• How does monday.com integration enhance their existing workflows?
• What time savings or efficiency gains will they experience?
• How does your platform extend monday.com's functionality?

⚠️ Marketplace Quality and Duplication Policy

At monday.com, our goal is to foster a robust, innovative, and high-quality ecosystem that delivers maximum value to our users. To ensure the marketplace remains a curated space of distinct, impactful solutions, we are updating our submission review criteria.

Moving forward, the app review team will no longer accept submissions that duplicate existing ecosystem functionality or integrations.

New Rejection Criteria:
To maintain our high standards, apps falling into the following categories will be rejected during the review process:

1. Redundant Third-Party Integrations We will no longer approve apps whose primary purpose is to integrate monday.com with a third-party product that already has an active integration in the marketplace. This includes, but is not limited to, new apps targeting:

Google tools (e.g., Drive, Calendar, Gmail)

Microsoft tools (e.g., Teams, Outlook, Excel)

WhatsApp

Shopify

Zendesk

Calendly

Zoom

Telegram

Any other existing integration currently available in the marketplace

2. Functional Duplication ("Clone" Apps) We will no longer accept apps that copy the core functionality of an existing marketplace app.

Note on Value Add: Making slight UI tweaks, minor feature additions, or superficial changes to an existing app's concept will not be considered "new value." Your app must introduce a substantially unique solution or serve an entirely different workflow to be approved.

What This Means for Developers:

Before you begin developing a new app, we strongly recommend that you thoroughly search the monday.com marketplace to ensure your concept does not conflict with these new guidelines.

Phase 2: Technical Scoping

Goal: Design your app's technical architecture and plan implementation details

During this phase, you'll define exactly which APIs, authentication methods, and framework components your app will use. This is one of the most critical phases, as proper technical scoping prevents changes later.

🚧

New apps built primarily using no-code platforms or AI-generated “vibe code” are not eligible for marketplace approval.

Authentication Strategy

Choose the authentication method that best fits your app's use case:

Phase 3: Building

Goal: Transform your technical plan into a working monday.com app

In the building phase, your team will build your app by applying all of the knowledge gained from the previous phase. This phase should go smoothly and efficiently if you have thoroughly scoped out your app.

Taking the integration recipe example from above, the building phase is where you will be creating your custom trigger, action, and field type blocks.

Iterative development

Build your app in focused iterations to catch issues early and adapt to discoveries:

Phase outcome

After completing this phase, you will have your new monday app that’s ready for submission to our apps review team. As such, we recommend preparing the graphical assets and marketing copy that will accompany your application in this phase as well.

Phase 4: App review

The last phase in the monday app development cycle is the review phase.

At this point, your app should be built and should be ready for submission to our apps marketplace. In the review phase, you can expect some feedback from our team on your app.

Phase outcome

Once finished, your app will be available in our marketplace for our users!
