Omnibus Evergreen Funds: Onboarding
What Monark sets up, what your platform builds, and the order to do it in before your first live Omnibus order.
These guides are for distribution and model portfolio platforms that place orders in evergreen funds through Monark Omnibus, for clients whose accounts are held at a custodian. Read them in order:
- Evergreen Funds: Onboarding (this section): how Omnibus works, how to connect, and what to check before going live
- Evergreen Fund Marketplace: client accounts and the fund catalogue
- Evergreen Fund Investing: pre-order requirements, orders, model orders, rebalancing, redemptions and positions
If you are new to Omnibus, start with the Omnibus Overview for how the platform works and the terms used throughout, then the Product Flow Overview for the lifecycle from onboarding to settlement.
Onboarding Steps
Some steps are carried out by Monark and some by your platform. Timing depends mostly on the custodian.
| Step | Who | What happens | Guide |
|---|---|---|---|
| Monark and you | Agree on the funds you plan to offer and the custodians that hold your clients' accounts | Product Flow Overview |
| Monark | Issues your sandbox API key. Request one at [email protected] | Integration Overview |
| Monark | Sets up each custodian as a Financial Institution under your platform and sets its custody model for each fund and share class. Makes sure a Cash and a DRIP omnibus account are in place at each fund's transfer agent, in the custodian's name or, in the MMM Securities master omnibus, in MMM Securities' name. Enables the funds it can trade, records the wire instructions the custodian uses for each fund, and agrees on settlement file formats and wire timing with the custodian. Any order fees and order limits are set per custodian | Product Flow Overview |
| You | List your Financial Institutions with GET /primary/v1/financial-institution and note each financialInstitutionId. Optionally add your own reference with PUT /primary/v1/financial-institution/reference | Integration Overview |
| You | Register an endpoint with POST /primary/v1/webhook, verify signatures and handle each Omnibus event | Webhooks |
| You | Client accounts, the fund catalogue and fund pages, pre-order requirements, orders and model orders, redemptions and positions | Evergreen Fund Marketplace, Evergreen Fund Investing |
| You | Take a model order from account creation to settlement in the sandbox, and exercise rejections and cancellations | Sandbox Walkthrough, Errors & Reason Codes |
| Monark and you | Review the checklist together. Monark issues your production API key and base URL | Go-Live Checklist |
