How can I leverage services partners for my integration partnerships?

Is this question asking how to leverage service partners to _build_ the integration partnerships? Or to have those services partners _facilitate/implement/properly set up_ integrations in the integration partnership? On the first front, we got our start by someone at the SaaS company we were doing partnerships with asking if we wanted to build out another integration for them. In that case we were paid directly, but it also came up just as a pure "solution" for an end customer. So in that case, look for service partners who have technical chops and show good knowledge of proper workflow management. Then either contract them directly or offer to broker an introduction and explain the situation. If they do a good job, list them as a preferred developer/integration vendor and voila! Now, if you're asking how to get them in the game to help augment/amplify your integration partnerships... That's where you've got to work with those integration partners to ask if they have a vendor/service partner program; then see if you can cross-pollinate/train. If there's something there, approach some of your services partners to see if they might be interested in cross-training and being listed as a specific software-related implementation partner, and pull them into an example deal (whatever the scenario was that prompted you to ask this question). You can/should also ask your services partners if they have expertise/use any of the tools you're interested in ("Do you have expertise in any of the following tools: [multi-select with all of your integration partnerships]", "If yes, do you want to be listed as an expert/implementer for that specific software as well?") Lots of options to explore. Just my two cents!

We typically introduce our tech partners to our service partners via partner slack and one-on-one so that service partners bring the tech integrations to their clients. We also facilitate enablement materials such as videos and webinars to make sure everyone knows how to use the integration and what it can do.

* Service partners offer a great opportunity with Integration partners in two areas:
 1. Augmenting the set up of tough legacy integrations. 
 2. Gaining utility from the integration directly in the product, and expanding the value customers get from the integration. 
 Bonus: Building Integrations for you to Integration Partners who don’t have interest or resources.

At the end of the day, your service partners represent an incredible wealth of knowledge as they are effective the voice of their customers (which are hopefully your customers too!). To me, the best way to leverage service partners for integration partnerships is by getting their insight into what integrations should be built, what integrations can be improved, and how/if the newly shipped integrations are helping their customers they way you envisioned.

Focus on those with skin in the game already for that stack/part of the stack. As an example, while at Amplitude our partner Feld M in EMEA created the Adobe Launch Integration (https://amplitude.com/blog/amplitude-adobe-extension). When a SP creates an integration like this, they garner extra credibility in the field. Large SI's do this frequently as well to differentiate their services around Large Technology partners, be it cloud/cloud management, Salesforce, Adobe, SAP and others. If you are a smaller startup, Regional SP's or Agencies may be the right fit to approach.
